The Lenz body heat system protects the body from cooling in key areas. The rcB 1200 lithium pack can be used to operate the Lenz Warmer Socks, Warmer Vest, Warmer Bandage, Warmer Gloves and LED system.

The batteries are simply fixed in place using snap buttons. Compact lithium packs heat the body, where it is particularly vulnerable to cold.

Heating power can be controlled directly on the lithium block or via the free smartphone app
