Engineered for today’s mountaineers, the Lightline Jacket remains a reference point for lightweight, technical down insulation. Its hooded construction and water-resistant outer provide dependable warmth and protection in sub-zero environments.

Filled with 700-fill power Pure Down, the jacket uses a stitched-through baffle design to maximise warmth while preventing down migration and cold spots—especially across key exposure areas like the shoulders, chest and hood. All virgin down is certified to the Responsible Down Standard (RDS) and sourced in line with our DOWN CODEX® commitment to animal welfare and high performance. Each jacket features a unique Trace Your Down code, giving full transparency over the origin, quality and fill power of the down used.

The lightweight, highly water-resistant Drilite Loft outer fabric enables full lofting of the down for maximum thermal efficiency, while shielding against melting snow and spindrift. Completely windproof and highly breathable, it ensures lasting comfort in severe mountain conditions.

Carefully tailored for effective layering without unnecessary bulk, the Lightline allows unrestricted movement whether carrying a pack, climbing with axes or handling ropes. Adjustable cuffs and a dual tether hem drawcord help seal in warmth and fine-tune the fit.

The fully insulated hood features a wired peak for added protection in harsh weather and can be zipped off when reduced weight and pack size are priorities. Three down panels shape the hood for a secure fit, while easy-to-use drawcords allow adjustment even with gloves.

A durable two-way YKK® moulded centre zip resists ice build-up and is backed by an internal baffle to lock in heat. Storage includes two zipped handwarmer pockets and an internal zipped security pocket for essentials.

Lightweight, warm and highly protective, the Lightline Jacket continues to set the standard for cold-weather insulation.
