RATING AND REVIEWS

Great pants, very comfortable!

4

I love these pants so far. The fit is nice and they are comfortable out on the water for the day. The only criticism I have is that the cargo pocket could be deeper and I would have liked a cargo pocket on the left leg too, not just one on the right. I would recommend these pants.

Best Pants Ever!

I love these pants! I've had a pair of the regular Ferosi pants for a couple years and they were my favorites. Decided to get the ones with the zip off legs for a backpacking trip. It poured rain and the rain pants I had over them were old and didn't work. When it stopped raining, I took the rain pants off and the ferosis were soaked. They dried faster than any gear I've ever had. I definitely recommend these pants.

I think I found my new favorite pants

There are now my go to pants for any longer climbing or hiking trips. The water repellency is still there after 5 washes and the fabric is stretchy making it super comfortable to active days. I thought it would be a little bulky and won't be suitable for anything other than shoulder season use but it is light enough to be great for warm weather use too. I would definitely buy it again.

Nice pants, but not for hiking, climbing, or backpacking

I use them for hiking and glacier climbing (in summer). I think the pants are quite comfortable, light, and fit great, but the lack of ankle zips is a huge disappointment. I was going to return them, but then I checked with my tailor and she is able to put ankle zips in. I don't understand the point of making a convertible pant with zip off legs without including ankle zips. After zipping the legs off, I cannot fit them over my climbing boots. I haven't tried, but I suspect they will fit over sneakers or running shoes since they have some stretch in them.

Great Product

These pants are great. The material is incredibly quick drying, offers full range of motion and plenty of elastic stretch to the waist so you can keep wearing them even if you go up in size for any other pants. They stay cool in the summer but plenty warm in the winter and from what I have seen so far, they are quite durable. I would recommend these to anyone for almost any use.

Pacific Crest Trail Thru/Hike with OR

4

I recently completed hiking the Pacific Crest Trail with as much OR gear because I love these products and wanted to see how they would hold up on a 5/month backpacking expedition. The truth was, after only 2 months on daily use and i mean daily, I had to switch them out to some pants I found in the thrift store because they began to deteriorate. But below you will find the positives and negatives of for these pants. Positives: 1. Water repellency: I loved how if i brushed up against a wet bush, the water would just bead down and off (sometimes into my shoes) but it would take a real shower to get water saturated. 2. Stretchiness/ this was ideal for moving over terrain, never lost its stretch. 3. Breathability/ I love shorts which is why I got the conversion pants because I can get HOT hiking. When using the pants in warmer weather as protection against mosquitoes, the breathability was there and I barely noticed that I was wearing pants. Wonderful quality. Negatives: 1. Pockets: In a long distance backpacking trip, you need various items to live in your pockets at all times for quick access. The ONLY zipper pocket on the right side was too small in my opinion and my mini pocket knife that I've had for YEARS quickly wore a hole in the pocket and fell out, as well as my chapstick. If there was more zipper pockets spread around the pants, I wouldn't have had to rely on this one small pocket to keep my secured items there, only to have them fall out through a hole. Overall, these are great weekend hiking pants, but I wouldn't advice them for a thru/hike, unless you purchase multiples and send them to yourself.

Love the pants, miss the zippers

Great pants/shorts. Comfortable for day long activities. The only thing they are missing are zippers on the bottom of the pants for getting them off over my boots. Add zippers and this is a 5 Stars pair of pants.

Iメve had a pair of the Ferossi shorts now for a while and have loved them, so when I saw the Ferossis were available as convertible pants, I had to order a pair. I was not disappointed as they just extend the comfort range of the shorts, just zip the bottoms on when the mornings or evenings are cool. Two zippered back pockets and a zippered thigh pocket along with the regular front pockets are nice. I'm 6' and 175 lbs and the 32s fit well. The shorts come down to my kneecaps with the bottoms zipped off. Bill Dudley OR Grassroots Athlete
