The Atomic Redster Heated Boot Bag 220V/110V is the smaller and lighter of our two race bags with integrated heating system. That said, with a capacity of 45L there’s still plenty of room for a pair of boots plus your gloves or socks. You can choose between Hot (70°C/150°F), Dry (60°C/130°F) and Warm (50°C/122°F), and you have the option of a regular DC plug or a plug that works in your car to keep the heat going. The extractable ground sheet makes sure you won’t get your socks wet when changing before or after a race. All this, plus two stowable rucksack straps and a shoulder strap, makes it really easy to carry to any race course in the world.
