Comfortable and adaptable, these midweight bottoms are perfect for layering, outdoor sports, or everyday cold-weather wear.

Designed for high-output cold-weather performance, the Men's Active Stretch Bottom combines four-way stretch with midweight warmth for unrestricted movement on the mountain or wherever the day takes you. Soft, comfort-knit fabric moves naturally with your body, while Acclimate Dry+ hydrophobic yarns wick moisture away from the skin quickly to keep you dry and comfortable through variable-intensity efforts.

Flat-seam stitching throughout minimizes irritation against the skin while maintaining durability and stretch over time. Layers easily under pants without bulk or works on its own in brisk weather — reliable warmth and moisture control from first chair to last run. No front fly.
