Whether you're in the Alps or the Himalayas, battling frigid temperatures during stop-and-go activity can be as challenging as the terrain. This lightweight midlayer is constructed of Polartec Thermal Pro High Loft fleece developed exclusively for The North Face to provide efficient thermal insulation in the coldest conditions. An innovative open-stitch mesh construction between the 1.5" fleece baffles effectively traps body heat and improves the overall warmth-to-weight ratio. Smooth, four-way stretch fleece panels are placed down the sides to maximize mobility on the mountain.
