Women's Lightweight Heated Jacket

From snowshoe days to the break at the summit, the light jacket goes the whole winter outing: worn on its own when the pace is slow, under a waterproof jacket when the cold sets in. Fitted cut, water-repellent puffer quilted with stitching to spread the fill over the whole upper body, high collar against the wind. Three heating zones, in the back and pockets, take over as soon as the pace slows. Discreet zips, custom elastic binding.
