Battling frigid temperatures during stop-and-go activity can be as challenging as the terrain. This lightweight mid-layer is constructed of Polartec Thermal Pro High Loft fleece 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 at the sides maximizes your mobility on the mountain.

  • Designed for alpine climbing and mountaineering
  • Exclusive Polartec low-density knit fabric minimizes weight and maximizes compressibility
