The Patagonia Capilene Thermal Weight Boot-Length Bottom moves to a heavier 4. 5-oz weight of the same Polartec Power Grid fabric this season, preventing sheerness while holding onto the odor control and anti-pilling performance from before. It layers just as well under snow pants on a chairlift day as it does running errands in the cold, with a boot-length cut and minimal seaming that stay smooth under any outer layer. What Our Gearhead(R) Experts Are Saying:"The fitted cut moves with me through every kick turn on the skin track, and I've stopped tugging the waistband back into place between transitions."
