The best way to turn gravity to your advantage is simply to surrender to its magnetic pull and let yourself go. For wild rides or controlled descents, the micro-grid fleece interior of our Capilene Thermal Weight provides the greatest warmth combined with the greatest breathability of any baselayer in our lineup. Soft, stretchy and compressible, the Polartec Power Gridfabric has a smooth face that glides beneath layers and a brushed fleece interior to warm your core, wick moisture and feel smooth against your skin. Capilene Thermal Weight is bluesign approved, has 92% recycled content and is treated with Polygiene permanent odor control. Features include a brushed elastic waistband for next-to-skin softness, a gusseted crotch for mobility, a functional fly, flatlock seams to minimize chafing and a 22-inch inseam for comfort with big boots.
