new favorite

    got this for my husband for his birthday, he loves this style of hat and it looks great! he used it for airsoft and his head stayed dry and safe from the sun, great purchase! it did run small, he usually wears large on most hats but he needed an xl

    Quick favorite

    • Familiarity: I've put it through the wringer

    This hat quickly became a favorite of mine due to the fantastic fit (large was perfect for me) and the convenience of being able to just shove it in a pocket if need be. The folding brim has been surprisingly convenient

    Good for a small dome and packable

    • Familiarity: I've put it through the wringer

    One of my favorite hats. Nice to have a good, packable hat for my small cranium. You can throw it in a bag and not worry about it. Provides good sun protection and breathability. My only knock on this is I've had some issues with actual sizing, i.e. I've always purchased a small, but they weren't all the same actual size.


      I like the style and it's comfortable. Contrary to the other reviews it does fit my head just right.

      Runs large :) or my head runs small

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: Runs large
      • Size Bought: XL

      Just received two, one in khaki and one in forest. Very prompt delivery thank you.

      Khaki - greyer than I expected, almost a tinge of green
      Forest - deep dark green

      XL - my head is 23.75" around (XL is for 24") and it is loose on my head. I can easily put a couple of fingers, both touching my head, between the band and my head. Being made of nylon, I don't expect it to shrink. I can make it smaller with a stitch or two, but expected something a little snugger. In future, a little elastic might be nice. This feels like it will fly off my head in a wind.

      Darius, Thank you for the review, and I am sorry it's just a tad too big for you!

      Happy Trails,

      ... from the Colorado sun and stays put in the wind, folds up nicely for packing and can be thrown in the wash when dirty, which is often. I am a size 7-1/4 and the large is snug, so I say that is running small - some elastic, or adjustment in the headband would be nice

      Perfect for hiking

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Medium

      I bought this hat in preparation for a road trip. I wore it every day. It is light & comfortable.

      The fit has changed.

      • Familiarity: I've used it several times
      • Fit: Runs small
      • Size Bought: XL

      I love these hats. I recently ordered my 3rd and 4th after losing my 2nd on a vacation.

      However, the sizing of the XL has changed markedly from the ones I bought in 2013 and 2014. It's now pretty darn snug and was a comfortable fit previously. To be honest, after receiving them I thought they'd sent L's but they're labeled XL. I normally fit 7 5/8 so by OR's charts these ought to work. But it's tight.

      I'm hoping they'll stretch out a bit after a few wearings.

      Great piece of gear

      • Familiarity: I've used it once or twice and have initial impressions
      • Size Bought: large

      super lightweight, stylish, folds up and fits in a small pocket, friggin LOVE this thing. No complaints from me. I got the large and have a 7 1/4" head by baseball cap standards. Also pic related. That was taken in heavy wind, cap stayed on, was impressed.

      Great piece of gear

      nice hat

      • Familiarity: I've used it several times
      • Fit: Runs large
      • Size Bought: Large

      I have quite the large head so I ordered an XL and it was larger than I normally buy (7 5/8 roughly or L/XL flex fit) to the point that I could tuck my ears into the band so I ordered a L to replace it and it's bigger than a normal large but pretty tight on my head. The depth of the cap is right on the money but I am hoping I will be able to stretch it out some without getting a headache. I needed something to fold up into my pack or back pocket for traveling and it does just that. Other than the size issue this is a great looking and functioning cap. A stretch band would be nice to fix the size issues.

      Awesome cap

      • Fit: True to size

      I love this cap. I have run in it and have used it for several years working as a kayak guide in coastal SC.

      It breathes well, rinses clean with ease and stows easily in back pocket. The short bill provides some shade and cuts glare reflecting off of the water, but doesn't interfere with large framed sunglasses.

      Good hat

        Good hat, very packable. Only gripe is trying to get the sizing right. I purchased the medium, and while it's a little snug, it's not uncomfortably so.

        Hey Matt - sizing is hard to get right when you are between sizes! Enjoy it anyway!

        Too Big or Too Small

        • Familiarity: I've put it through the wringer
        • Fit: Runs large
        • Size Bought: Large

        I've had ~5 of these hats in the past several years, and it keeps getting better.
        Only gripe is that the difference between the M and L is huge.
        M constricts my head, and L is loose enough to fly off in a gust.
        Even a little loose, this hat is still my go-to for hiking and backpacking.

        Hey there -

        Thank you for the review! Let me pass this feedback on to OR.

        Great Hat!

        • Familiarity: I've put it through the wringer
        • Fit: True to size

        Although I have rarely folded the cap up, it has this capability and fits in a cargo pocket with room to spare. Due to the fabric, it doesn't tend to keep wrinkles or creases. You can yank the cap out of a pocket and it looks fine when you put it on.

        The fabric sheds water at least to some extent. I have been rained on and it has never seemed to get soaked. I'm not sure how breathable it is, but I've never found it too warm.

        I now have four of these hats. (One is a ferrosi with the zippered pocket on the side, which is also more shallow than this cap's style.) Not just for the great outdoors, I'll wear these anytime!

        Hey Wesley,
        Thank you for the great review! There is a reason this hat is one of our top sellers! Interesting about not getting wet... it isnt waterproof, but it does fit well, breathe well, and the foldable brim is rad!

        Thank you for taking the time to write,

        The Go-to

        • Familiarity: I've put it through the wringer
        • Fit: True to size

        The Radar Pocket Cap has been my go-to hat for outdoor adventure for the better part of a decade. I never go for a climbing, hiking, or canyoneering trip without the Radar on my head.
        Useful in all conditions this hat especially shines in the desert where it provides ample sun protection without making you feel overheated.
        The foldable bill enables the Radar Pocket Cap to easily slip into a pack or pocket when the time comes to put on a helmet.

        nice hat

        • Familiarity: I've put it through the wringer
        • Fit: Runs large
        • Size Bought: L

        It does run a bit large... Nice hat, I prefer to add more curve to the bill. Beads water off really well. Great for tossing in the pack, super slim and light.

        Great hat, made for the outdoors!

        • Familiarity: I've used it several times
        • Fit: True to size
        • Size Bought: XL

        Love the feel and build of this hat. Looks great on but can be tossed in a backpack without fear of ruining the shape/fit. Initially I purchased the large (based on reviews posted here) but found that it was too small. So in my case it certainly didn't run large. I had to return for the XL which fit perfectly! The hat has no elasticity so I can definitely see why the fit of this hat is such a question. It either fits or it doesn't. Once you find your size it's a great hat!
