Hybrid merino wool baselayer bottoms with breathable, next-to-skin comfort, and quick-drying performance perfect for any cold-weather pursuit.

A layering essential for keeping young adventurers warm and comfy when the temps drop, the Basis Power Wool™ Tights are year-round, cold-conditions baselayer bottoms that manage moisture during high-output pursuits. Made with Polartec® Power Wool™ fabric, the Basis Tights feature a highly breathable, layered construction that offers the benefits of both natural and synthetic fibers. Soft, ultra-fine merino wool next to skin wicks moisture, while a quick-drying polyester outer 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. Flatlock seams make for chafe-free comfort when they’re running around the neighborhood or zooming down the groomers.

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.
