The Men's Black Ice Jacket is probably the most versatile boxwall down jacket ever created. It's both light in weight and extremely functional. It features boxwall panels that have been designed to follow the contours of the body, reducing the number of cold spots and creating even panels of high quality goose down. To really help protect the down from the weather and rucksack strap compression it has an extra layer of PrimaLoft protection over the shoulders, hood top and forearms. The Black Ice is perfect for cold winter days and nights either on the move or resting. Should you get caught out in rain, the outer fabric also has a highly weather resistant inner coating ensuring that the down plumes will stay dry and continue lofting.
