Regulate temps and stay comfortable on cold winter days with our foundational merino boxer.

On cold winter days, a merino wool blend boxer brief regulates internal temps, wicks moisture and offers premium comfort next-to-skin. Our snug-fitting, athletic Basis Power Wool™ design finds that right thermal space between too hot and too cold. A gusseted crotch allows unrestricted range and flatlock seams reduce layering friction under ski pants or our Fernos Knicker. The merino/poly blend resists odor and dries quickly during high-output activity whether lapping lines or earning turns.

Polartec® Power Wool™ Knit Grid Jersey, 69% Polyester, 31% Wool, 153g/m2

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.
