Built for alpinists who count grams but refuse to compromise on warmth, the Trollveggen Down800 Super Light Jacket is Norrona’s lightest and most packable down insulation piece. Designed for demanding mountaineering objectives yet versatile enough for everyday adventures, it performs effortlessly as both a mid-layer and a stand-alone outer layer across all four seasons.

At its core is Norrona’s lightweight aeroDownproof face fabric — a 100% recycled 10D nylon that balances weather resistance, durability, and an exceptionally soft hand feel. This ultralight shell protects premium 800+ fill power duck down, delivering outstanding warmth-to-weight efficiency and compressibility for easy packing in a harness or pack.

The responsibly sourced, RDS-certified 90/10 down is treated with Hyperdry technology, reducing moisture absorption and accelerating drying time when conditions turn damp. Elastic cuffs and hem seal in warmth, while the high protective collar provides critical insulation in exposed terrain. A longer back cut enhances coverage and comfort during movement, making the jacket equally reliable on steep ascents and cold belays.

This is insulation distilled to its essence: lightweight, dependable, and purpose-built for the mountains.
