Yet what makes these jackets even more special are their Hybrid capabilities. Paired to Gerbing’s optional 12V FlexPack Battery (which fits in its own pocket), the LT Jackets can deliver heat both on and off the bike. You can plug into the bike, as with any Gerbing’s motorcycle product. Or step off the bike and the power of the FlexPack takes over. Controlled by a 3-position remote control it can deliver up to 3 hours of heat. Get back on the bike, plug in, and the FlexPack charges up from the bike’s electrical system while you ride. Or if you want, ride wirelessly and just power the jacket from the FlexPack.
