Customer Reviews

They've gotten smaller. :( (Review by Trevor)

Love this hat, and after losing one on a trip tried to replace it. But the XL now fits like the L used to a few years ago. Too small and returned. Other than that it's a great hat and I've still got one of the old ones that I wear quite a bit.

The BEST Backpacking hat!! (Review by Tami)

I took this hat with me along a 2,650 mile thru hike of the PCT. I loved that when I didn't need the hat I could easily store it in my backpack with out it being bulky and awkward to carry. Even in the desert heat my head never got too sweaty or hot - the lightweight fabric is super comfortable. Another great product from OR!

bad hat (Review by kevin)

I had the same problem with this hat as I had with the Swift hat. The bill is cut asymetrically so that one side is longer and dips much farther down than the other side. Not sure if that's a bizarre new style or just poor quality control by OR. After 10 minutes of wear it annoyed me so much I gave it away.

Buy this now. (Review by Keith)

i bought this hat for two reasons, rain and rain. This hat kept me dry, and kept my glasses spot free during a stormy bicycle commute. The XL was big at first,( typically no hat fits me,( I was a green dot in football helmets)) after a run through the wash, the hat shrank just enough to be perfect... Equate this to new Levi's.

Great hat for any weather (Review by Adam)

My first cap went all over the place with me and received tons of comments about where to get one - I've even had one person like it so much they took it out of the rental car in Detroit.
I've had four now, couple different colors in fact. I have worn it in heat, everyday at work in pouring rain and even though it's not designed for rain it keeps my head dry. It has gone everywhere with me, and have a back up just in case I loose another or one is taken again. I'd recommend -light, durable, comfortable, and dry.

A Revelation (Review by NewDeal)

When you want to pack small and light, a traditional baseball cap is pretty inconvenient. I got the Radar cap to fill that need, thinking it would be a utilitarian piece to keep the sun out of my eyes, my head dry, and cover up messy hair (ok, so I'm a little vain). I was surprised--it's actually a very stylish hat. I wear it out and about as much as on the trail, and get many compliments. And that folding brim... why every hat doesn't have it, I don't know.

Regarding its water resistant capabilities--I've worn this hat in some pretty heavy storms and it has kept my head perfectly dry. As a test, I even inverted the hat and filled it with water. I didn't notice any drips. Conclusion: this hat is, for all intents and purposes, waterproof. The only drawback I've found is that it holds in my perspiration on hot days. For that reason, I plan to buy the version with vents.

Like an "old friend" (Review by Matt)

I've owned this hat for a while, and decided it's finally time for a review. This thing goes with me everywhere. It's super light, really comfortable, and effective. I get countless compliments on the hat, and people are amazed when I show them how the brim folds. It's like they've been living under a rock all their lives. Some folks have mentioned the water resistant properties as being bad - however, I've found that it does just fine as long as you are not in a down pour. No, it is not waterPROOF, but it's not made to be. The functionality (spelling, I've had a few beeeeers) is great for blocking that big ball `o fire in the sky, and keeping light rain out of my eyes. Plus it folds down to the size of a taco and slips into a pocket or pack very nicely. I recommend the Radar Pocket Cap for anyone that wants a hat that is truly functional and not cumbersome. You can't go wrong with something that simply works.

Almost perfect! (Review by MJS)

Love this hat. Light-weight, great for traveling, versatile, easy to clean. 4 stars instead of 5 only because the hat is a bit deeper than I'd prefer - I have a big grape on my shoulders, and when I put it on, it fits well in terms of diameter, but there's still a little bit of space between the top of my head and the hat - not a deal-breaker, just not perfection. Love the fold, too.

Radar Pocket Cap (Review by By Mixed Beard)

This is a typical OR product. High quality, great price, and useful. This is my go to hat for travel and backpacking. It's folds in the middle at the brim, slips straight into any pocket, then comes out and pops right back into form. I've brought baseball caps with me hiking before and you wreck the brim if you try and stuff them anywhere, and I've brough those "running" hats with me and once that brim gets out of shape it's never the same. I like the military style brim, not because it's becoming a trendy style but because it packs down even smaller and weighs less than a full brim would. But it definitely has a short brim, so be prepared.

Radar Pocket Cap (Review by By Never Look Back)

I LOVE this hat! For the last 2 months, it has been the only one I wear. It works great for sun protection, but also is surprisingly good in the rain. I got soaked hiking a couple of times, and the hat kept my head completely dry. Love how easily I can fold it up and throw it in my pack. It will definitely be coming to this weekend's camping trip w/ me! PS. Not sure why some people say this hat doesn't fit well. It comes in S-XL sizes. Just need to get the right size.

Radar Pocket Cap (Review by By Adventure Team 420)

Another killer product from Outdoor Research! It packs down so small, it will fit in a pack side pocket,so you can put in on in the morning after a red eye flight to a exotic destination, cover your bed head, and look fresh and stylish!

Radar Pocket Cap (Review by By ranger girl)

I bought this hat to wear on a six month trip to Nepal, Thailand and New Zealand. I pretty much wore it every day, rain or shine. I used it while hiking, on the beach, or in town. It keeps the sun and rain off of your face and packs down amazingly small. It's a one size fits all, and it fit me perfectly but it may not fit people who have smaller heads. Because I wore it so much the green color faded from the elements. I think it looks cool faded but others may not.

Radar Pocket Cap (Review by By Bass Player Chris)

Good hat, only thing is it feels a little loose. Pity it doesn't have any sort of rain proof lining.Other than that, stylish, and comfortable, very good in strong sun.

Radar Pocket Cap (Review by By Sean)

I bought this hat for a 3 week Europe tour. It was late May so weather changes were quick, but it did good in both sun and rain. Perfect size to pack in a cargo pocket. It just got a lot of wear in the Bahamas. I think I will buy one in another colour.

Radar Pocket Cap (Review by By Paul the Boater)

I love this cap because it's light, comfortable, and goes everywhere I do. It folds down and will fit in my back pocket, drybag, or in my jacket no prob. It's thin and light enough to throw a beanie over it when it get cold and is super comfortable even in hot summer weather.
