The Seahawk sun hat from Shelta is a Boonie-style, made from a lightweight nylon fabric which offers 50 spf protection.
In addition to a stiffened front brim, the Seahawk offers a removable strap system which allows the wearer to configure the hat in various ways as well as an internal pouch in the crown.
The Seahawk is offered in an interesting camouflage pattern, which integrates the shapes of the continents, as well as a Tan and Dark Grey.
