Review on Sun Hats For Men/Women, Wide Brim Bucket Hat Waterproof Breathable Packable Boonie Hat For Fishing UPF 50 UV Protection by Trey Crosland

Got the olive green and it's a very nice looking color. Although it is not cotton, the fabric is nice, not "plasticky". It's foldable and came out the package without wrinkles, unlike the cotton version I ordered elsewhere. The size is "one size fits most" and 22-24" circumference, and it fit me and my husband just fine (sits a bit lower on my head than his). Very happy with this purchase.
