In a thermally-efficient box wall construction, this Jagged Ice Jacket is just the ticket for extremely cold conditions.

Upping the ante on insulation, there’s a Barrier Lite RS outer fabric filled with 650+ fill power down. The down creates thousands of tiny air pockets which trap warm air and retain heat, keeping your core very warm in chilly winter weather.

The lower profile stitched through sleeves and semi-elasticated cuffs are cut out for the climb, allowing you to move your arms and hands whilst belaying or climbing. You can put a helmet on over the roll-away, arched and wider than usual insulated hood.
