This ESEE Adventure Cap is a nice top-quality cap. The front has been enhanced with a piece of Velcro (7.5x5 cm) with a cool ESEE patch on top. You are, of course, free to also attach a different patch.
The back is made from polyester mesh while the body of the cap is made from 100% cotton. The mesh provides you with the necessary ventilation to make sure you can also wear when it is very warm out.
