Great casual/hiking pant. (Review by Aaron)

These pants fit great! I am 175# 6' tall 31"waist and body builders thighs. These pants fit very comfortably, they are not tight on my legs, but not baggy either. I have worn them camping over multiple days, backpacking above 40F, and even to work with a blazer and tie!

I have two pairs and have owned them for over two years. I even spilled flaming bacon grease on one pair! It saved my leg (my hand got partial and full burns, but the bacon was worth it!), however that pair is now relegated to hiking as a result of damage from the flaming bacon grease, but they do smell amazing!

I would strongly recommend these pants for casual wear and hiking, they are very durable and comfortable. They have held up much better than my hiking buddies comparable Columbia's. In fact he is buying a pair of Ferrosi pants as a result of observing mine over the past few years.

My bum looks wonderful in these (Review by Carl)

I took these on an 18 day rafting trip through the Grand Canyon in February. Aside from the obvious benefits from how these pants accentuate my curves, they performed wonderfully. They are very comfortable to be wearing under a drysuit or for hiking up any of the many side canyons.

One feature that I especially loved were the adjustable elastics at the ankles. These were essential while playing polish horseshoes to keep the pants above the calf, and prevent the intrusion of the ever-present sand.

One feature that I believe could be improved is their drying ability. On days that I was foolish enough not to wear a drysuit, or just from walking though streams, they inevitably got wet. Afterwards, the drying time always took a little longer then I had hoped. My other pants are straight nylon and dry much faster. This material difference, however, is a trade off to how well the Ferrosis stretch and move with your body.

Great Pants (Review by Jennifer)

I've been looking for pants like these for ages. I took these from my boyfriend because he didn't like them. They fit me quite well. I have a 30 inch waist, 34 inch hip, and a 30 inch inseam, so they work quite well for women with narrow hips too. They are so comfortable, I bought two more pairs.

Great! (Review by Chris)

These pants have been great for working in the yard, hiking in snow and general do everything casual pants. I picked up the short length, which was nice to have proper length inseam and when paired with long underwear bottoms, make a great hike in the snow pant. True 4 season versatility. Greatly recommend. In my opinion, fits true to listed dimensions and still allowed lightweight bottoms to be worn beneath.

Love em (Review by Matt T)

Very comfortable and functional. For Texas weather they can be worn pretty much year round. They're so breathable I'll even wager I'll be wearing them in the summer. The only downside I've experienced so far is that they haven't stood up to my abuse as well as I had hoped. They frayed and became very fuzzy in high wear areas within a few weeks. Admittedly though, I was wearing them while performing construction in our climbing gym... probably the wrong choice of pants for that so I won't knock them too much. In cooler temps, I love that they easily fit over a layer of thermals and remain comfortable.

Best pants ever (Review by Jason)

Let me start by saying these pants do not owe me a thing. I climb, I hike, and I bushwhack, and these pants they do it all with me.
They are extremely durable, stand up to "sharps" and I have never regretted wearing them (never too hot or too cold)

The glue on pocket failed and I contemplated sending them, back, but while waiting I snagged the pocked at it was 100% removed.... well now the pants look new, just without the pocket.

I find the size gap to be quite large. The 32 requiring hemming, and a belt, and the 30 fitting like spandex.

These are again my most favorite pair of pants I have ever owned.
Please send sample Ferrosi hoodie/jacket/or Summit hooded jacket. I will review it :) and wear it every day.

I have a bubble butt (Review by Bubble Butt)

I have a bubble butt, and these fit perfect. Pants from Arcteryx and Mtn Hardwear and Patagonia are way to tight around my butt and look like yoga pants even though the waist fits. These are perfect fit in the waist and butt. Baggy enough to still have a relaxed fit, but tight enough that you can use them in alpine and off trail and not worry about snags.

Fantastic (Review by aj)

These are amazing! I have rather large thighs due to a wrestling background and there is elasticity in that region which helps make bending/crouching a breeze.
In addition, these pants are relatively water-proof. I have gone out of my way to purposely step in puddles and haven't had water seep through.

Love this product.

Great for warmer weather climbing! (Review by Joseph)

These pants are surprisingly tough. I've worn them on stiff cragging, many longer alpine outings, and a week in the Pickets range (cascades), and they are still going strong. Really breathable, they stay relatively cool when it gets warm. They are really comfortable to wear for long periods, and I have found they articulate well while climbing. Highly recommend them for summer alpine!

Excellent for everything (Review by Joe O)

These pants are excellent for almost every outdoor activity. I mostly wear mine climbing and they can perform in a variety of temps and conditions. These pants have proven to be very durable, I've had them for a year of hard use guiding rock and personal climbing. They are also super comfortable. I used to really like the Patagonia Rock Craft pant but the Ferrosi have a better fit and Patagonia doesn't make those anymore. I'm 6.2 and 185 lbs, the 32 fits me very well.

Good, but don't plan on using them multiple years (Review by BackpackingLeprachan )

I bought a pair of these pants in march of 2016 (I'm 5'7 and 195 lbs and got a size large that fit awesome) and was told by my friends that they were the best pants around for backpacking, climbing, etc. I work in a profession where I consistently am doing that type of stuff and am teaching troubled teens how to do it. I have got to say that they held up really well for the first 6 months and I had nothing but compliments to give these pants, however after not having them for even a year they're already causing me some trouble.

I have worn the pants probably 45+ days and now the stiching is coming undone literally everywhere. The back pocket stitching is falling apart, the stiching in the crotch area is coming undone and I am pretty confident that within the next 5 or so times of wearing these pants they will no longer be functional. I love all my OR gear and expected these pants to do well, however in my eyes they fell short of my expectations in a big way.

Light weight and tough (Review by MATTHEW)

I love these pants. They're very thin so they're great in heat. I wore them in 80 degree weather and they're great. When temperature dropped into the 30s I wished I had on there pants when not moving.

A Known Commodity (Review by Glenn)

I've worn out several pairs of these over the years. They seem to have a little less stretch than comparables (i.e. Schoeller Dynamic) which I'm certain helps a great deal with durability.
They look nice enough I can roll into the office after a morning hike or hunt and get by. Fit is what it is, the cut has stayed the same over the years which is all you can ask for.

Best pants ever (Review by Shane)

These pants are amazing. I use them on almost all of my hikes and they are always the perfect temperature. Extremely comfortable and shed light rain amazingly. Even when they are soaked through they are comfy.

Great pants for the outdoor enthusiast! (Review by LifesNextAdventures)

Very stretchy material which makes the pants great for rock climbing, hiking, or just everyday pants! Very comfortable but form fitting. Packable and hold up well in most weather (light rain, snow, etc).
Only complaint i have is the legs and groin area feel a bit too tight for my comfort. I wear these pants about once every three to four days and anytime i'm in the backcountry they are in my bag. So far they are holding up very well like most gear i buy from OR. Thanks for a great product Outdoor Research!

Perfect pants! (Review by Eric)

Mes pantalons préféré! Je les portes pratiquement tout les jours. Léger, respirant et surtout confortable! Idéal pour l'escalade au gym ou à l'extérieur.

Great Pants (Review by Derek)

I love these pants. They block a little wind, shed a little rain, are tough and very comfortable. I have had 2 pairs over several years. Put a hole in one during a fall with an axe and it never tore any further after that. My only "complaint" is the thigh pocket has a vertical zipper. You have to be careful when opening it so your phone doesn't fall out, especially when several hundred feet off the deck. I'd personally like a more diagonal or horizontal zipper opening for this pocket.

Fantastic pants (Review by Bill)

For me a perfect pant. Construction, styling, colour. The fabric is light yet has enough structure to look like a stylish pair of pants. These pants are not your ordinary hiking pants.

(Posted on 11/30/15)

I love these pants! (Review by Adam)

These are definitely my favorite off work pants, I wear these hiking and doing everything else outdoors. Even indoors these pants feel great - they are cool,dry, and fit like another layer of skin (that I never had). Super comfortable and dependable.
I will say if there are two things I have small issues with - they run a little bit large and a little bit long (the length doesn't bother me though with the elastic on the bottom of the pants).

I highly recommend these pants for any type of rain or cooler weather (maybe not winter without a thermal layer underneath).

Great Pant!! (Review by Matt)

I have been using this pant in both rock and alpine environments. I am 6'1" and weigh 185 lbs and they fit perfect. They have great articulation and length is just perfect, not too long, not too short. I would recommend this pant to anyone looking for a great all around pant in the summertime rock/alpine environment.

(Posted on 6/7/15)

Great pants, but not for tall people (yet) (Review by Matt)

I am 6.1 and wear size 32. This would be definitely great pants, but they are way too short in Regular. OR, please (please! please! please!) start making them in LONG version also. I'll buy two as soon as you offer them in LONG. Otherwise great quality as always!

(Posted on 5/16/15)

Great in so many ways (Review by Doc-Rush)

These pants are near perfect for so many things. They're tougher than they look, dry quick, and move with you. The elastic line in the ankle cuff works great and disappears when you don't need it.

I'd like deeper hand pockets, but they do the job.

(Posted on 3/26/15)

A Great regular outdoor pant (Review by Bestbuilder)

These are my everyday pant I wear them to work, Backpacking, hiking, scrambling, Scouting, yes, everyday. They are well made, fit true to size, durable and give just enough when bending or stretching to get that toe hold that puts stress on the crotch of regular pants.
I would give them Five stars if the front pockets were a little deeper (so my whole hand fit inside) and if they had two thigh zip pockets instead of one.

No going back (Review by Jacob)

I started wearing OR pants about a year and a half ago and ever since I tried on these pants I cant make myself go back to regular jeans or khakis. I hate when pants bind and don't move with you, the ferrosi fabric is the exact opposite. I climb mostly in the SE region of the US and these pants surprisingly hold up great on sandstone. I thought they would shred for sure when I got them but the first pair I bought is still going strong. I couldn't recommend a product or company more. I've been more than happy with every pair of pants I've received from OR. Only complaint is they don't restock often enough!

hard wearing, well designed (Review by gitrdun)

I beat and use the heck out of my gear - from big walls to guiding on alpine rock (lots of butt scooting and seated belays), and can attest to the quality of construction, materials, and subtle design features that make the difference to people who spend time climbing technical rock in the mountains and the crag. I like that the boot cuffs fit snug around the top of my Trangos so they keep scree and snow out without needing stirrup strap attachment points. The fabric stretches with your body and the fit is technical without being at all constrictive. As stated before, the fabric holds up extremely well on rough granite, drys fast, and seems to keep me comfortable in a very wide temperature range - from hot summer days to cold pre-dawn starts for fall alpine ice. A note to the manufacturer: Do not change anything about these pants! I'm on my 3rd pair but have not honored their incredible warranty because they've far surpassed any pant I have tried so far with durability.

Very comfortable, but.... (Review by Andrew)

I bought these in November (2014) and have worn them to work probably 2 dozen times. My first issue is the fit. I bought a size 32, but these are 3 inches too big, even out of the wash. EVERY pair of soft shell pants I currently own are a 32 and fit wonderfully, except these. As an instructor and outdoor educator, I need to have a professional look about me. I bought these specifically for work because they looked great, though now they look as though I have been cllimbing granite off-widths in them. The knee to thigh area on both legs have completely peeled. I am sceptical that they would withstand the torments of the alpine environments and technical pursuits that I live for.

Best clothing piece ever (Review by dennis)

I wore these pants hiking in texas hill country for two weeks, then spent a week in the mountain, the temperature range was 94 down to 26 and snow! These pants are amazing! They are cool in the heat and dry fast, but are comfortable in the cold, and cut the wind! They held up to thorns, rock, and some serious bushwhacking!. They now go everywhere with me.

Mens Ferrosi Pants (Review by Jim)

I have owned these pants for a few months and have been very happy with them. I am 6'3, 240 lbs and I have the pewter 38 size pants. I have used these pants primarily for summer hikes in the Pacific Northwest and so far I have not had any issues with rain or warm weather. I am not sure I would wear these pants in cold and wet weather due to the fact they are very thin. I do wish OR would have included loops for their suspenders. After hiking for a while the waist will stretch and if you do not have a belt or suspenders the waist line will fall.

Finest in Ferrosi (Review by Brimstonian)

Perfect fit ... The material is soft and flexible for all activities whether climbing, biking, hiking or working. I like the cut of the pants with double seams for withstanding the extremes of all situations while in the stretch ... if you get my drift....

Only suggestion for OR... Need more inventory!

Near Perfection (Review by Ryan)

I have three pairs, and have used them over the course of a year. They have been trekking in Bhutan, climbing 14'ers in Colorado, as well as survived 130+F temps in southern Iraq. They still look brand new, wear extremely well, and were well suited for all these environments.

My only complains are the slightly tight crotch and the difficulty of finding them In Stock at OR. Otherwise...perfect.

Great pants - if you carry a purse (Review by funNactive)

I almost love these pants. They would be 5 Stars if they had good pockets. I am 5'6" 140 lbs. athletic build. These pants fit great; not too tight, not too loose. - The only problem that diminishes their versatility are the pockets. They are way too small - a Samsung Galaxy S3/S4 will not fit comfortably in them.

If you intend to only use them for your outdoor athletic pursuits when you have a pack with you, they are great. But they have a casual look to them that that would make them versatile enough for around town wear if the pockets were deeper.

The material is light weight & durable - great for hot weather or when it is cooling down & you need to block wind or light precipitation.

Wearing them more and more (Review by Jacob)

These are the kind of technical pants that are so comfortable I find myself wearing them more and more to places that would probably be more suited to dress jeans or slacks here in Europe. They are great for hiking and climbing, and while I think they look like technical pants, my wife likes how they look and says that she thinks they're OK to wear out around town. Which is fortunate, because I've been doing just that a lot these days. Breathable, stretchy, athletic cut. My only change would be some sort of drawstring or better yet a simple lateral waste-tightening system because, while the fit is better on the second pair that I bought (I needed a 32 instead of a 34, and it was worth it to get a second pair) sometimes wearing a belt with a backpack or a harness isn't very comfortable and it would be nice to be able to cinch them down a little for some activities. The Ferrosi pants haven't shown any signs of abrasion or snagging after taking them climbing 8 times and hiking countless times, and they've washed well.

Love these pants! I work outdoors and the ferrosi pants are extremely comfortable - never bind or bunch up.

3 season go to pants (Review by Michael)

I wore these for the better part of a year traveling by bus and train and climbing everything mostly granite and limestone. When living abroad you spend a lot of time in hot cramped buses or trains with extended hiking/hitch hiking(see riding in the back of bongo trucks) from bus and train stations to climbing destinations. I personally loved these pants because of how well they breath and the comfortable fit making them perfect for three season wear, they block wind well and shed light rain with ease. If you do manage to soak them through they dry with in the hour. The low profile waist fits great under a harness or the waist belt of your pack and the ankle cinch straps are a great finishing touch for climbers who want to keep their pants off their heels while tied into the sharp end. After a year of use they are showing some fuzziness on the knees and other high wear areas but that's to be expected of any light weight material when beaten against granite repeatedly.

Great climbing pants (Review by adkeditor)

I just returned from a road trip in which I climbed at five locales in four states. I wore my Ferrosi pants on every climb, and they held up great. They're so lightweight and stretchy that you hardly notice them. They also can take a beating. I abraded my knees a few times, but the pants did not tear. Added bonus: the blood washed right out.

Men's Ferrosi Pants (Review by By Billiam)

OR makes the best fitting pants out of any company I've tried. (and I've tried a bunch of companies) The Ferrosi pants are great for warmer endeavors but work for slightly colder days as well. On the hot days, they breathe like you are almost wearing shorts. I have worn these pants on everything from desert towers, to crag sessions at the local crags (Durango area) and Many days in the mountains spring through fall. I Love these pants!!! The only issue I have seen was a rear pocket getting a hole (after a year of use) and OR had a replacement sent before the we could even send the busted pants to them! So, OR's customer service is awesome as well. Bill Grasse

Men's Ferrosi Pants (Review by By Canoe Bob)

These pants have it all. They look great, are very comfortable, wear like iron, are super light weight and pack into the size of a soda can. I wore a pair of these pants most days on a 5 week Arctic canoe trip and on my return home, wore them out to dinner with friends. With the curved waist and articulated knees, these pants are designed to move with you. The lightweight ferrosi material also provides good protection from the wind.All in all, for outdoors activities or urban adventuring, the Mens Ferrosi Pants are a great choice.

Men's Ferrosi Pants (Review by By aleday)

Fit varies across all manufacturers, but overall, I typically wear a 33" waist/ 34" inseam pants. The 34 long variety of this pant fits perfectly with a belt. Great weighted and selected fabric to climb splitter cracks in the creek in October and April, and long haul alpine rock days in the Sierra summer. On the approach or high efforts, a little sweat is expected, and the pants dry quickly or can be rolled up briefly. roll down the cuff and the cool breeze at belays aren't a problem and the stretch is ideal for flexibility when negotiating rock moves. If the front pockets had zippers the pant would be even better.

Men's Ferrosi Pants (Review by By Graham Bagman)

These pants quickly became my go to pant for warm weather climbing. They are super light but stop wind well, so they are warm enough for spring to fall climbing. I also like that they don't look awful: the curved waistband makes the pants very flattering, or at least that's what my girlfriend tells me!I love these pants for climbing because of the drawcord on the inside of the cuff. It's super low profile and at first I didn't even know they were there, but I love being able to have tight cuffs for climbing without looking like a skinny jeans wearing hipster the rest of the time. The pockets are also nice and slim and don't become a problem after a few hours of wearing a harness. The side pocket is well placed for me to use while I've got my harness on. I got my first pair of these pants as a gift, but I liked them so much I went and bought another pair.

Men's Ferrosi Pants (Review by By PatH)

I just wore these guiding a 21 day June trip in the Bob Marshall. These were just what I was looking for. I wanted a pant that didn't look like I was wearing some kind of parachute pant when I put gaiters on and that were more slimming in the legs and these were just that. I'm not quite sure what kind of belt someone would wear with these because they will support wearing a very wide one. I got the 30s and am a 30+ inseam and they fit great. I wore these with the Cascadia Gaters and I noticed there was some wear occurring on the shin area from the gaiter so I wouldn't want to do that with them all the time. They repelled water well and dried quick after stream crossings.

Men's Ferrosi Pants (Review by By Mr. Canoehead)

I've just started wearing the pants in an outdoor setting (they were too nice at first wearing them around town) and they are not only comfortable but also very durable. I wore them on an early Spring canoe outing and the material has good stretch and very tough. Front pockets aren't the best for storing keys, wallet and such. A little tight. But that's a very small point.

Men's Ferrosi Pants (Review by By Ian)

Just to let you know! I'm a 30" inch inseam and the pants come in 32" so I had to have my tailor remove the bungee cord hem in order to size them to a 30" inseam. Other than loosing the bungee cord hem (no big deal) they tailored beautifully. I find bungee cord hems useless. If you need protection wear gators.

Men's Ferrosi Pants (Review by By Ian)

A leisure walk around town or Nordic Walking the Ferrosi Pant is a winner. I'm a 34" and the pant fits like a glove (not to tight, not to loose). Just a few things to note: 1)Front pockets lack depth (for wallets, keys etc...), 2) Navy or steel blue would be nice and 3)How about a belt. I own both the Mushroom and Pewter and will be purchasing a pair in Black.

Men's Ferrosi Pants (Review by By Climbing Logan)

I've only had these pants for a week and I already love them! The are soft and as comfortable and pajamas and the material feels like it is born to last. I love the zip hip pockets and thigh pocket. The front pockets may be a little shallow or hard to get into. Overall I expect these to be my new favorites for hiking and climbing in cooler weather. I can't wait to wear them again, may have to order another pair in another color!
