Smartwool Intraknit Thermal Merino Base Layer Bottom // Women's
The Smartwool Intraknit Thermal Merino Base Layer Bottom for Women takes a more technical approach to staying warm. Instead of relying on the same fabric construction throughout, Smartwool uses its advanced Intraknit technology to strategically integrate insulation, ventilation, and stretch into a single garment. The result is a base layer that provides warmth where you need it and breathability where you're most likely to overheat.
The Merino wool and polyester blend brings together the natural temperature regulation, moisture management, and odor resistance of wool with the durability and quicker drying performance of synthetic fibers. Seamlessly knit mesh ventilation zones help release excess heat during demanding activities, while the body-mapped construction moves naturally with you.
The women's-specific slim fit follows the contours of your body, with a mid-rise waist and minimal seams for comfortable layering underneath ski or snowboard pants. The 3D-knit construction also provides excellent flexibility, making these particularly well suited for active skiing, touring, and other cold-weather activities that involve plenty of movement.
If you're looking for something more technical than a traditional wool base layer, Intraknit is a meaningful upgrade. You still get the warmth and comfort of Merino wool, but with a more deliberate balance of insulation, ventilation, and mobility that makes a noticeable difference when you're working hard in cold conditions.
