We added carbon fiber heating elements to a kick-ass technical puffy, and the ‘Ectotherm’ was born.

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.
