For fast-and-light mountain days, the Norrona Trollveggen Down800 Women's Hood Jacket brings the brand's most packable hooded down warmth. Premium high fill-power down delivers a lot of heat for almost no weight, and a hood adds coverage when the temperature drops. It is the featherweight insulator that stows to nothing and is always worth bringing.

Why we like it:

The packability is the appeal; it stuffs down small and weighs next to nothing, so it makes every alpine pack, now with a hood for those extra-cold moments. Premium down does the heavy lifting.

Features and Functions:

The women's Trollveggen Down800 Hood is insulated with 800-plus fill-power down for a top warmth-to-weight ratio, under a lightweight aeroDownproof face fabric that adds weather protection and a soft hand with good durability. An insulated hood adds coverage, and it packs down small for easy carry.

Fit and Sizing:

A technical, athletic women's 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 hooded belay or summit layer, the Trollveggen Down800 Hood is best at maximum packable warmth for mountaineering and alpine days. The insulator for women who count every gram.
