Bring the heat without overheating in the WarmCube™ Active Novus Jacket. This innovative synthetic puffy offers warmth when you want it and when you need it in our lightest, featherless jacket to date—perfect as a go-to active winter piece when you're stopping, and especially when you're going in the cold. WarmCube™ Active insulation tech regulates internal temps by circulating air through the jacket while you're moving and trapping heat inside internal cubes so you stay warm when you come to a halt. What does that mean? This breathable puffer will keep you cool when the pace or incline picks up from the trail to the city grid, and warm when you stop for a snack break or post-shred beers in the parking lot. Throw on a shell and you're ready for bell to bell resort laps.
