Stay silent, stay dry, stay comfortable. . . and they'll never hear you coming.  The GORE™ OPTIFADE™ Concealment Subalpine hides a waterproof/breathable GORE-TEX 3-layer, 20-denier fabric, adding little weight and offering unconstrained, silent movement.  Unzip the YKK pit vents and head up that hill with an integrated Drop-Away adjustable hood ready to deploy when needed.  This is the first item you'll throw onto your gear pile every time.  Match it with the Dewpoint Pants and you'll get head-to-toe durable, protection weighing in at only 23 ounces for both.
