Product details

The Keep The Heat thermal underwear from Mountain Warehouse is a high-quality functional base layer specifically designed for active individuals. It offers an optimal combination of comfort and functionality, making it ideal for cold weather conditions. Made from a thoughtfully crafted blend of materials, this underwear provides excellent thermal insulation while remaining lightweight and breathable. The moisture-wicking properties keep the skin dry, and the quick-drying technology ensures that the underwear stays comfortable even during intense activities. The elastic cuffs at the ankles and the stretchy waistband guarantee a comfortable fit and prevent slipping while wearing. This thermal underwear is therefore the perfect choice for outdoor activities or as an additional layer during the cold season.

  • Isotherm technology for optimal thermal insulation
  • Moisture-wicking and quick-drying
