Built for vertical days and long traverses, the Trollveggen Down800 Super Light Vest delivers essential core warmth with almost no weight penalty. Designed for mountaineering yet versatile enough for year-round use, it layers effortlessly over a base layer or under a shell, or stands alone when conditions allow.

The vest is constructed with Norrona’s aeroDownproof face fabric—an ultra-light 10D recycled nylon that balances weather resistance, durability, and a soft, quiet hand feel. Inside, RDS-certified ExpeDRY™ 800+ fill power down provides exceptional warmth-to-weight efficiency and compresses down to almost nothing in a pack. The Hyperdry-treated down resists moisture uptake, dries faster, and maintains loft when conditions turn damp.

A technical fit with an extended back length keeps the core protected during movement, while a high protective collar seals in warmth. Elastic binding at the hem ensures a secure, low-profile fit that works seamlessly with harnesses and packs. Thoughtfully minimalist, this vest is built to disappear when you don’t need it—and perform when you do.
