The 4KAAD Thermobelt PRO in yellow is a double-insulated belt that keeps your sports drink hot or cold during training and racing. It holds 1 liter of liquid and has a top pocket for your phone, ski wax, energy bars, or other small stuff.   

This thermobelt is super popular with World Cup athletes in cross-country skiing and biathlon because of its comfortable fit and smart features. The silicone insert in the flap stops the bottle from slipping, and the elastic mesh on top gives you extra storage.
