Designed to be a staple in your layering system year-round. When used as a base layer in cold conditions, the elastic Polartec Powergrid material wicks excess moisture away from the skin to create a dry, warm barrier next to the skin. In warmer temperatures, you can use it as a lightweight layer for summer climbing. Offset shoulder seams reduce contact with pressure points when wearing a backpack. An elastic chest pocket offers quick access to essentials. Designed in collaboration with our athletes, the Eiger Nordwand Advanced FL Half Zip Pull is a versatile layer for alpine objectives.Features:- Fit: Athletic fit.Specifications:- Recycled.
