So, like a lot of Arcteryx gear, this jacket seems to have taken a direct aim at fixing the problem of a minority of users. Namely, the offset top of the main zipper which some people don't like having right in front of their face when the weather is wet/cold. But I think solving the zipper issue created other issues with this jacket. The collar seems strangely stiff on one side if you have it zipped but don't have the hood up. If you leave it open, the flap is longer on one side and tends to flap more. Full disclosure: I bought this jacket, but have received others from Gore for participation in the MountainTechs program since 2007.
