An excellent lightweight cap that breathes well, does the work, and surprisingly soaks up a lot a sweat during hot weather runs. I'm happy with the purchase and would only recommend that at some point they consider a more flexible, soft bill.

Item came quickly and the hat is high quality. The brim is stiff though, so no smushing it into your pockets like some other foldable choices out there.
