Rated 4 out of 5 by from Missing features from earlier cap I have an old REI cap that has two features missing in this one that I just purchased. 1) the underside of the bill in my old cap is darker color to help with glare - missing in the new cap. 2) there is a real sweatband piece in my old cap but none in this new one. It is lighter than the old style though and uses a velcro strap adjustment vs. the plastic latch on the old cap. Hopefully it will wear and last as long as the old model.

Rated 5 out of 5 by from Cute, light, and functional - esp for small heads bought this hat a few months ago for walks and dayhikes and it immediately became my favorite. lightweight, it offers good sun protection for sunny days while also keeping my head cool. AND looks good on my small head. the blue color is very nice, better than the typical colors offered by hats (black, khaki, bright neon green). also love that the size adjuster is with a buckle rather than velcro. the vecro on my previous favorite hiking cap wore out and kept coming loose, so the hat would not stay on my head. before it started to wear out, it would catch on and snag hoodies, sweaters, etc -- very annoying. i somehow lost this hat a few weeks ago. i thought i could make it without replacing by borrowing an extra black cap from my partner. while that cap is functional, it is not cute. so now i am here to buy a replacement.

Rated 5 out of 5 by from Lightweight sun protection, easy to hand wash I got this to use for running in Houston, TX (hot and humid!), and it's exceeded my expectations so far. The visor is big enough to keep mid-day sun off my eyes, the fabric is very breathable, and it's super easy to hand wash after each run. It also has little loops at the sides, which I didn't notice when I bought it, but they seem like they'd hold sunglasses securely.

Rated 5 out of 5 by from Love it for running Bought it because the bill is super soft and flexible. Love this hat. Please add more vibrant colors for running so I can be seen.

Rated 5 out of 5 by from Lightweight hat I'm a female and I bought this hat for backpacking. So light and comfy. It has sunglasses loops on both sides. The sunglasses fit a little awkwardly but it's nice to have a place to put them if I don't have them on a cord. Ponytail hole in the back and easy to adjust on the head. I bought the whitish color. Very packable.

Rated 5 out of 5 by from I Forget I'm Wearing it I've had this for a few weeks now and I'm very happy with the hat. It is incredibly lightweight, so light that I forget I'm wearing a hat. It's very breathable and keeps my head cool. A real bonus is that it can be folded or rolled up so it goes on all the trips. I love it.

Rated 5 out of 5 by from Hike, train and workouts are easier! great product! Light weight and perfect fit. If you are like me...I love hats that are skin friendly ( Esp. on the forehead ), soft, breathable and fold-able. Home run here!!!

Rated 5 out of 5 by from Lightweight is an understatement Featherweight-light (i.e. a couple ounces at the most I would guess). Soft, comfortable, packable. Looks cool. Does the job.
