Montbell Stainless Mesh Cap - GreyThe Montbell Stainless Mesh Cap is not your average five panel cap. Not only does it have that big ol' sunshade down the back, but it's made from lightweight stainless steel coated mesh. Think of it like ultralight chainmail reflecting heat and providing excellent breathability during hot days out on the trail. It's packable too making it a good thru hiking option.
