Skiers that are looking for the best breathability in a jacket need to take a gander at Strafe's Nomad Jacket.  It's a 3L eVent fabric jacket that is plenty waterproof and extremely breathable.  Unlike NeoShell and Gore-Tex, eVent doesn't require a polyurethane film to attract water to the waterproof/breathable membrane.  Since there is one less step for moisture to go through eVent is quicker to breathe - critical for skiers that are sweating and we all sweat.

If you're skinning you're sweating, and if you're skinning you need a place to put your skins when it's time to descend.  Strafe put to pack friendly pockets on the chest that are large enough to hold skins and keep them warm for your next ascent.
