The Heat Vest 3.0 Unisex is a pleasantly warm, padded vest for almost any season – ideal for everyday wear, outdoor activities, and travel. The innovative Fellex® Fast Heat Insulation with carbon fibers stores heat and reflects it back to your body. Combined with the durable, robust outer material, this creates a versatile vest that reliably accompanies you through changing temperatures – simple, comfortable, and functional.
In addition, the vest is part of the Lenz Body Heat System, allowing it to be upgraded into a heated vest with optional batteries. The included Heat Pads then provide hours of comfortable warmth at the push of a button or conveniently via the free Lenz Heat App with 9 heat levels. The warmth is delivered exactly where you need it most: in the lower back and kidney area, where it is reliably retained close to the body thanks to the wind guard. Combined with an additional layer of clothing, you enjoy comforting warmth and high comfort even on the coldest days.
