Warmth and Performance for Alpine Pursuits

Designed for the dedicated alpine athlete, the Patagonia Men's Capilene Thermal Weight Boot-Length Bottoms offer the greatest warmth-to-weight ratio in Patagonia's entire baselayer lineup. Whether you are tackling high-exertion alpine routes, winter mountaineering, or spending freezing nights in a tent, these bottoms are built to perform in the most demanding conditions.

At the core of this baselayer is Polartec Power Grid fabric, which features a smooth face that slides easily under your outer layers and a brushed, lofted-grid interior. This design traps warm air against your skin while actively wicking moisture away to keep you dry and comfortable. The boot-length cut is specifically designed to sit above your ski or mountaineering boots, eliminating bunching and pressure points for all-day comfort. With a gusseted crotch for unimpeded mobility, flatlock seams to reduce chafing, and permanent odor control, these bottoms are a must-have for any serious backcountry user.

• Polartec Power Grid Fabric: Provides the perfect balance of lightweight warmth, breathability, and moisture-wicking performance.
• Boot-Length Design: Optimized to sit above your ski or mountain boots, preventing unwanted bulk and pressure points.
