FIRE-PANTLINER heated underpants developed to keep you warm in cold weather. Ideal for wearing under ski pants, trousers, jeans!
The special heating elements in the knee and kidney area are close to the skin, allowing the heat to transfer ideally to the body. The pant liners are perfectly insulated by the layers of clothing worn over the underpants, keeping the heat in.
The battery pack goes into the right-hand pocket. The heat is turned on and regulated (3 heat settings) by pressing the push-button switch on the underpants waist band. Depending on the setting, each battery gives two to five hours of heat.
The heated underpants are yet another innovative solution to keep you warm and comfortable, whether during sporting activities or in everyday life!
