We added carbon fiber heating elements to a technical puffy, and the Ectotherm was born. Powered by your bike's 12V battery for heat that lasts as long as the ride.










We added carbon fiber heating elements to a kick-ass technical puffy, and the ‘Ectotherm’ was born. The updated V2.0 brings a redesigned lower-profile controller and cable management pocket, plus two new battery-saving modes to extend off-bike capabilities when used with a power bank.
When the wind chill is at its peak, the Ectotherm’s bike-powered 6-panel carbon-fiber 3.5Amps/42w heating system will keep you warm on high alpine passes and long, cold pavement stretches. When you crawl out of your tent on frigid mornings, the Ectotherm performs as a super warm stand-alone insulator with 100g body-mapped synthetic PrimaLoft Gold insulation with Cross Core Technology.
V2.0's upgraded heat settings include a Low Power Mode, where the heating elements pulse, gradually increasing and decreasing heat, helping maximize battery life when plugged into an external power bank. In Timer Mode, an auto-off setting is activated to maintain your desired heat level at 20/30/60 minute presets, which is handy for falling asleep on bitter nights and not using up all your battery.
