L3 Warm pants W

Engineered for prolonged exposure in extreme cold, snow, and sleet.

The L3 Warm pants are insulated with recycled 200 g Polyester loft and rated for temperatures down to -55°C / -67°F. Professionally field tested in Arctic Norway, they provide reliable thermal protection while maintaining a low-bulk construction that supports natural movement. A durable Nylon shell with a waterproof rating of 20,000 mm protects against sustained exposure to snow, wind, and moisture.

Two-way water-sealed side zippers allow temperature regulation during activity. Integrated snow gaiters with shoelace hooks and a large lower-leg opening keep the pants dry and allow them to fit over large winter boots. Reinforcements along the lower inner leg increase resistance to friction during repeated use.

Removable suspenders and adjustable waist and ankles create a secure fit that works easily with layered clothing.

Two large thigh compartments provide secure and accessible storage.

Pair them with the L3 Warm jacket for complete protection in extreme winter conditions.
