Explore Gokyo base layers and thermal wear for men and women, designed for winter trekking, Himalayan travel, high-altitude conditions and cold-weather adventures. Worn close to the skin, a base layer forms the foundation of an effective layering system beneath fleece, insulation and weather-protection jackets.
Thermal Base Layers for Trekking & Winter
Base layers help retain warmth while managing moisture produced during activity. Choose thermal tops and bottoms according to expected temperature, altitude, activity level and the other layers in your clothing system.
Men’s & Women’s Thermal Tops and Bottoms
The collection includes thermal tops and bottoms for different cold-weather needs, from versatile winter travel and trekking to more demanding high-altitude conditions. Matching upper and lower layers provide complete next-to-skin coverage when temperatures fall.
How to Layer for Cold Weather
Start with a suitable thermal base layer, add fleece or another insulating mid-layer, then use an insulated or weather-protection outer jacket when required. Adjust the system as temperature, wind and exertion change.
