Norrona's lightest and most packable down jacket, the Trollveggen Down800 Super Light Men's Jacket is built for fast-and-light mountain days. High fill-power down delivers serious warmth for almost no weight, all in a feathery shell that stuffs down to nothing. It is the just-in-case insulator you barely notice in your pack until the cold hits.

Why we like it:

The warmth-to-weight ratio is the whole story; premium high fill-power down packs an incredible amount of heat into a jacket that weighs next to nothing. It disappears into a pack, which is exactly what you want on a long mountaineering push.

Features and Functions:

The Trollveggen Down800 is insulated with 800-plus fill-power down for maximum warmth-to-weight performance, wrapped in a lightweight aeroDownproof face fabric that adds weather protection and a soft touch with excellent durability for the weight. The result is one of the most packable down jackets Norrona makes.

Fit and Sizing:

A technical, athletic fit layers over a baselayer or thin midlayer. True to size, cut close to keep weight and bulk down.

Bottom Line:

As a fast-and-light belay or summit layer, the Trollveggen Down800 is best at maximum packable warmth for mountaineering and alpine days. The insulator you bring when every gram counts.
