We added carbon fiber heating elements to a kick-ass technical puffy, and the ‘Ectotherm’ was born. The new Ectotherm V2.0 introduces heating functionality updates, providing more versatility in use, both on and off the bike.

When you’re sitting around the campfire or lounging in your tent, it’s a super warm insulator with 100g body-mapped synthetic PrimaLoft Gold insulation with Cross Core Technology. Connected to the bike, it adds a 6-panel carbon-fiber 3.5Amps/42w heating system powered by the bike. That extra warmth takes the edge off long, cold, wet, pavement stretches; keeps you warm on high alpine passes; adds new enjoyment to early spring and late fall trips, and ensures you’re ready for anything a multi-year/multi-season RTW journey can dish out.

The Ectotherm is your solution for staying sane and happy when the weather turns brutal. The name comes from Ectothermic, a scientific term for animals that exchange body heat with external sources. Like a lizard basking on a hot rock.
