Like ducking into a warm Refugio during a pushing storm, this versatile, toasty pullover keeps your core temperature regulated and your spirits high even when the temperatures and weather want to bring you down. 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 30-92% recycled content and is treated with Polygiene permanent odor control. Features include a self-fabric collar with internal neck tape for chafe-free comfort, full underarm gussets for unhindered shoulder mobility, elastic thumb loops for secure hand coverage, flatlock seams to minimize chafing, offset shoulder and side seams to lie smoothly beneath pack straps, and a drop tail for additional coverage.
