Great concept! Love the zipper on the side, I put my car keys, money, credit card in in the pocket (all at once) the hat is still comfortable and doesn’t have a bulge...HOWEVER- the cap isn’t deep so it’s easy to fly off the head when running or when it’s windy out. Also- the material is paperbaggy- thick, doesn’t move well, isn’t super soft but doesn’t affect the comfort of the hat.
