On Mount Athabasca’s north face, storms sneaking in from the west go unnoticed until suddenly your route turns into a maelstrom of snow, wind and whipping ropes. Keep your inner thermostat turned up with this quick-wicking baselayer made from Capilene 3 Midweight fabric to provide excellent insulation and next-to-skin comfort. Brushed on the inside for warmth, this fabric is soft and compressible and has a smooth knit face that glides easily under layers. Details include a zip-neck for easy climate control, tuckable drop-tail construction and thumb loops for secure hand coverage. Made of a 5.4-oz Polartec Power Dry 100% polyester double knit, with Polygiene permanent odor control. Fabric is bluesign approved.
