Patagonia M's Cap Thermal Weight Bottoms

Low-Bulk Thermal Baselayer Bottoms for Cold Conditions

The Patagonia M's Cap Thermal Weight Bottoms are built for highly breathable warmth, moisture management, and easy layering in cold weather. Their Polartec® Power Grid® construction helps trap body heat while moving sweat during high-output activity.

Polartec® Power Grid® Warmth and Breathability

The smooth outer face layers easily under waders, ski pants, hunting layers, or shells, while the open-grid interior provides warmth, airflow, and moisture-wicking performance next to skin. HeiQ® Mint odor control helps maintain freshness during long days and repeat wear.

Stretch Comfort for Active Layering

Stretch fabric and a gusseted crotch support natural movement, while the low-bulk quick-dry waistband feels soft against the skin. Minimal seams help reduce chafing, and the functional fly adds convenience during extended use.
