A hybrid merino wool baselayer that manages moisture and keeps you dry during any high-output, cold-weather pursuits.

A year-round, cold-conditions baselayer that manages moisture during high-output pursuits on foot, skis or two wheels, the Women's Basis Power Wool™ Zip Neck features a highly breathable, layered construction that offers the benefits of both natural and synthetic fibers. Made in the US with Polartec® Power Wool™ fabric, the Basis features soft, ultra-fine merino wool next-to-skin to wick moisture, and a quick-drying polyester outer that adds strength and durability. The fabric also features a high-efficiency grid backer, which traps warm air, aids in moisture transfer and makes for faster drying. The classic zip-neck design provides added coverage and quick ventilation, while flatlock seams make for chafe-free comfort when you’re on the move.

Polartec® Power Wool™ fabric keeps you warm and dry during year round aerobic activities with an innovative bi-component knit that combines the distinct advantages of natural and synthetic fibers. An isolated merino wool interior and a synthetic fiber exterior create a hybrid construction that optimizes wicking, breathability, dry times, odor resistance and durability. The comfy wool interior provides warmth even when wet and is highly breathable, while hydrophobic polyester reduces dry times and offers durability, resulting in a textile that performs under any conditions, all year long.
