Keep your stems warm at work or at rest with the Patagonia Men's Capilene Thermal Weight Bottoms. Don't be that kid who used to wear shorts and a hoody in a snowstorm. Equally at home during high-exertion alpine routes or freezing nights in a sleeping bag, the micro-grid fleece interior of the Capilene® Thermal Weight provides the greatest warmth combined with the greatest breathability of any baselayer in the Patagonia lineup. Soft, stretchy and compressible, Polartec® Power Grid fabric has a smooth face that glides beneath layers and a brushed-fleece interior to warm your core, wick moisture and feel smooth against your skin. This fabric also has 30–92% recycled content and is treated with Polygiene®: permanent odor control. These bottoms aren't bulky, the waistband and leg seams lay flat; plus, there's even a crotch gusset for mobility. Pair them with your favorite pants when you're in the backcountry or at the crag; layer them while you're active in cold-weather or shredding the slopes.
