For active alpine endeavors, you'll appreciate the warmth, wicking, breathability, and packability of the Beast Quick Strike Cap. Made from the same materials as our Ninja Suit Pro II, this handy head-covering features top + front panels built from weather resistant DryTech 3D™ stretch softshell, while the side panels and ear flaps are cut from thermodynamic AirTech 3D-Eco™. The result is a versatile hat that keeps you comfortable as you move through the mountains.
