Product details

The Keep The Heat thermal underwear from Mountain Warehouse is a high-quality functional base layer specifically designed for cold weather conditions. It provides optimal thermal insulation and is ideal for outdoor activities or as an additional layer under everyday clothing. The combination of acrylic, polyester, viscose, and elastane ensures a comfortable fit and feel. The underwear is lightweight and moisture-wicking, making it particularly comfortable even during intense movement. Thanks to its quick-drying properties, the skin stays dry and comfortable, while the elastic cuffs at the ankles ensure a secure fit. This thermal underwear is an excellent choice for anyone who values functionality and comfort.
