Thanks to their thin design, the heated trousers from the Lenz Body Heat System fit under any trousers, whether casual or sports trousers. The heating elements are not noticeably located in the front thigh area and ensure pleasant heat development. The fluffy inner plush of the Heat Pants 2.0 ensures that heat is distributed evenly and offers additional comfort.
The lithium packs are attached above the belt waistband and, depending on the battery type, ensure heat development for up to 11 hours.
