Nice adjustable strap
Size: One Size, Color: (015) Halo Gray / / Astro Pink
Okay cap with adjustable strap and lightweight material. Doesn’t hold its shape well. But otherwise it’s a okay cap to throw on for sun protection .

Product is as described, love the material and it’s true to size. The shape is very nice and the material is sun protective which is good to control sweating in your head.
