It is made from medium-weight Polartec Power Grid material, which keeps you warm, is elastic and has a waffle structure on the inside that efficiently transfers moisture outwards. The Aenergy Pulloverâ€s smooth outer material means you can easily wear other clothing items over it. Itâ€s half-length zipper enables good ventilation. Flat seams ensure fewer pressure points and make the pullover really comfortable to wear – a versatile mid-layer for all your activities.
