The problem
The cold truth

Three layers. Still cold.

Thermal, fleece, parka, and the wind still finds your back. Bulk slows you down and traps sweat, and that sweat is what chills you an hour later.

  • Bulky layers restrict every movement
  • Hand warmers fade in minutes
  • Sweat under layers makes you colder
9 zones

Heat where your body loses it.

Carbon-fiber panels sit across your collar, back and hand pockets, the places your body sheds heat first. You stay warm without the bulk.

  • 9 heating panels
  • Thin, flexible panels you can't feel
  • Even warmth, no hot spots
Plug & play

Press once. Warm in 30 seconds.

Plug the power bank into the inside pocket, hold the chest button for three seconds, then tap to cycle High, Medium and Low. The light shows the level at a glance.

  • 3 heat levels, color-coded light
  • Zippered inner pocket holds the power bank
  • Works with most 5V USB power banks
All-day

Commute. Trail. Game day.

Up to 10 hours of heat on Low from one charge, a high zip neck that seals out wind, and a shell light enough to pack.

  • Up to 10 hours per charge on Low
  • High-neck zip seals in core heat
  • Windproof, water-resistant shell for wind and light snow
Plug In, Zip Up
