Durability
The Helly Hansen Sogn is well built and stretchy fabrics always hold up a little better than lighter, more rigid fabrics.

Weatherproofness
The Helly Hansen Sogn is on par with a long hem, long sleeves, and a waterproof-breathable fabric. The lightweight synthetic insulation is always welcome when wet conditions rule, though we were never able to wet this jacket out, even in some nasty driving snow at Jackson Hole. 

Bells and Whistles
The H2Flow system is a great feature and the Sogn also has six well-placed pockets, one of which contains a tethered goggle chamois. You can attach ski pants via a pair of hooks on the powder skirt to make, effectively, a snow-proof onesie. We like the high visibility, fluorescent panel on the hood brow—a good way to keep track of your group in a whiteout.

Function
We love this jacket for its relatively moderate insulation and freeride fit—the stretchy fabric also helps keep it from being restrictive.

Breathability
Helly Hansen’s H2Flow system punches holes in the sheet of insulation, making for better circulation, especially when the mesh-backed pit zips are cracked. That came in handy on some steamy warm spring days in Aspen. The pit zips could be a bit bigger though.
