Crafted from a fleece Technostretch fabric, this thermal top comes with 4-way stretch for increased range of motion for strenuous climbs or scrambling over obstacles. Thermal insulation keeps you warm while remaining highly breathable for all-day comfort. And the 3D waffle-grid structure effectively wicks moisture away when you ramp up the intensity. A UV-protection finish defends you from the sun's harmful rays in exposed conditions. Cool off or conserve heat with the partial zip down the front. And you can securely store small items in the zipped chest pocket. The Stretch Color 3 Zip Maglia Top for women is the perfect layer to wear under a heavy jacket while winter mountaineering or on its own for spring skiing.
