The all-new WarmCube Active Novus 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 for all your stop and go winter fun. This never-before-seen 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. You can breathe easy on cold-weather hikes, and you'll stay warm without needing to add layers after pitching the tent on your cold-weather camping trip.
