Designed as a waterproof, breathable protective jacket with its DRYEDGE™ 2L membrane and welded seams, this active hiking hat keeps out wind and surprise rainfall in the mountains, courtesy of its ext ra-wide and highly protective brim. Lightweight and super-supple, the RAINPROOF hat can easily roll up or be placed flat in its storage pocket, and for a snug fit has an adjustable chin strap - which can be removed for everyday use.
