Laugh at the cold. Sneer at the wind. With C.W.S., you can hunt through a blizzard if you have to! Extreme comfort in the field comes from advanced engineering. RedHead® C.W.S. (Cold Weather System) gear is built around Bone-Dry® -- the ultimate waterproof, windproof, breathable membrane. Its advanced hydrophilic technology is based on a chemical chain reaction between moisture molecules and nonporous film. Molecules of perspiration are absorbed and transported to the outside of the membrane, blocking out water from the outside. The membrane also limits air exchange; even the stiffest winds can't penetrate your clothing.RedHead® Bone-Dry® C.W.S. Insulated Pants feature quiet, Bone-Dry® construction with a smooth poly lining in both legs; 150 gram Thinsulate™ Insulation; articulated highback kidney flap for extra warmth; standup waist with belt loops and rubberized grip strip; zipper fly; 2 front pockets; 2 side zipper cargo pockets; leg zippers with storm flap; and hook 'n' loop tabs. YKK® zippers used throughout. Machine wash. Imported. RedHead® Bone-Dry® C.W.S.
