Lenz RCB 1400 Lithium Pack One Color, One Size

The Lenz RCB 1400 Lithium Pack provides up to 14 hours of reliable, powerful heat at the touch of a button. The battery packs work with our Lenz heated socks, vests, gloves, and other Lenz heated systems, and we can easily control the temperature either on the pack itself, or through the free smartphone app. The 14-hour battery life keeps us comfortable during long days at the resort, and the compact design can be easily concealed beneath our layers.
