Ice Climber's Dream Jacket.

The men's lightweight ALPHA IS Jacket offers insulated mobility for cold-weather climbing enthusiasts and frigid days on the slopes or in the city. The durable 2-layer Gore-Tex shell is waterproof, windproof, and breathable. Synthetic insulation tucked inside taled seams is water repellent, providing warmth without absorbing moisture. Extra padding in the body and shoulders adds warmth. Articulation provides enhanced movement, critical when scaling ice walls.
