Makalu Polarec ZT Base Layer Top - Women

The Makalu Base Layer is made for when things get serious. Colder, higher, longer. Its brushed inner grid traps body heat while staying breathable — locking in warmth without feeling heavy. It’s warmer than our K2 layer and designed to be the foundation of your cold-weather system: worn directly against skin, under insulation or shells. Ideal for summit climbs over 5,000m, winter treks, and expedition photography where movement pauses but the cold doesn’t. Thermal brushed interior for maximum heat retention Moisture-wicking exterior to stay dry under pressure Flatlock seams prevent chafing under layers Fit optimized for inner layering in extreme cold
