Product details

The Keep The Heat thermal underwear from Mountain Warehouse is a high-quality functional base layer specifically designed for cold winter conditions. It provides optimal thermal insulation, ensuring that body temperature is maintained even in low temperatures. The combination of acrylic, polyester, viscose, and elastane offers a comfortable fit and high wearing comfort. The underwear is lightweight and moisture-wicking, making it ideal for outdoor sports activities. Thanks to its quick-drying properties, the skin stays dry and comfortable even during intense movements. The elastic waistband and ankle cuffs ensure a secure fit and prevent slipping while wearing. This thermal underwear is therefore the perfect choice for anyone looking to stay active during the cold season.

  • Isotherm technology for optimal thermal insulation
