Men's Lightline Down Jacket
The iconic and continuing bestseller, this technical duvet jacket is ideal for freezing conditions anywhere in the world.
Built to meet the demands of modern mountaineers, the Lightline Jacket continues to set the benchmark for lightweight, technical duvet jackets. Its hooded design and water-resistant shell offer exceptional warmth and protection in sub-zero conditions.
Information
The Lightline Jacket uses 700-fill power Pure Down held in place by stitched-through baffle construction to optimise warmth and prevent down migration that can lead to cold spots, particularly in vulnerable areas such as the shoulders, chest, and hood. All of our down is minimally treated and is DOWN CODEX approved, meaning it’s sourced through a transparent and carefully audited supply chain.
The lightweight and highly water-resistant Drilite Loft outer fabric allows the down to loft to its full potential, providing maximum warmth while protecting against melting snow and howling spindrift. Drilite Loft offers complete wind resistance and excellent breathability, keeping you warm and comfortable even in the most severe conditions.
The Mountain fit is carefully designed for effective layering while reducing unnecessary bulk that can feel restrictive, allowing for complete freedom of movement whether shouldering a pack, swinging axes or coiling ropes. An elasticated hem drawcord and adjustable cuffs seal out the cold and help fine-tune the fit.
A fully insulated hood with a wired peak provides an invaluable defence against the elements in severe conditions. It can be zipped off to reduce weight and pack size when necessary. Three down panels optimise the hood to fit around the head, and drawcords allow for easy additional adjustment, even with gloves on.
A reliable two-way YKK moulded centre zip is resilient against ice build-up and is reinforced by an internal baffle to seal in heat. Internally, a zipped security pocket stores essentials, while two hand warmer pockets keep fingers toasty at camp or store items requiring quick access when moving.
Lightweight, warm and highly protective, the Lightline remains a benchmark piece for cold-weather insulation.
