The warmest, most breathable baselayer with minimal bulk.

When the temperature drops out of your comfort zone but your plans call for plenty of movement, the micro-grid fleece interior of our new Capilene Thermal Weight provides the greatest warmth combined with the greatest breathability of any baselayer in our lineup. The Polar tec® Power Grid™ fabric has a smooth face for easy layering, is bluesign® approved, has 30-92% recycled polyester content, and is treated with Polygiene® permanent odor control so your par tners won’t boot you out of the snow cave.

Features a 2-layer anatomically shaped hood for comfort under a helmet (and a ponytail exit on the women’s style). The kissing welt zipper provides comfort against skin, and the offset shoulder seams are comfortable under pack straps. Details include neck tape, locker loop, flatlock seams and hidden elastic thumb loops.
