Smartwool Women's Intraknit Thermal Merino Wool Crew - Medium

The Smartwool Women's Intraknit Thermal Merino Wool Base Layer Crew delivers lightweight warmth without bulk for extreme cold-weather pursuits. Built with Merino Sport yarns and a 3D-knit construction, this slim fit crew features gender-specific ventilation strategically placed to regulate body temperature and manage moisture during high-intensity activities. The Intraknit Thermal design balances breathability with insulation, keeping you dry and comfortable whether you're mountaineering, backcountry skiing, or training in frigid conditions. The crew neck and form-fitting cut maximise movement through the arms and chest whilst creating a sleek silhouette under jackets and shells. Medium sizing fits a 86 cm chest with 81 cm arm length for an ideal fit on taller frames.
