Pros: Breathes well, great fit & stretch, useful hood adjustments, Packs light & tight
Cons: Hip pockets too shallow, mesh laminates under shoulder panels rough on bottom/mid-layers, worthless arm pocket
I agree with the vast majority of what Finndog has to say in his review, and it's obvious he's used the Koven Plus enough to know the jacket.
As for GearGuide's concerns w/ durability: I've got 2.5 seasons' use out of the jacket now, have worn it extensively with a pack, and crashed it a few times, and it is still in fantastic shape.
If your definition of hard-core skiing involves earning your turns or even hiking to hit the side-country, this jacket blows away any of the Gore-tex or Windstopper jackets in my closet for breathability.
If your take on hardcore skiing involves frequently getting snagged on trees, rocks, or lots of careless abuse just 'cuz you can't be bothered to take care of your gear, then Cloudveil's regular Koven jacket or their RPK jacket would be your better bet (beware the RPK's hood though: lousy fit!).
A few minor caveats / additions to Finndog's findings, based on my tall, lanky body type, and personal predilections:
1) Length: I would have liked the jacket to be an inch or two longer for extra coverage when cinched up at the hem. The powderskirt does a good job of keeping out the snow, but for use with a pack, or use with non-waterproof pants in changing weather where hip protection is a plus, a little more length would be nice.
In all fairness, this is a jacket, not a parka, and I'm a slender 6'1" and wearing the size large, so those not quite as tall won't have my concerns.
2) the shoulder-top panels Finndog is calling "vents": the mesh panels laminated on the underside of the shoulders helps the jacket "stay put" under pack straps, which I like. When skiing in warmer weather, however, I tend to wear just a single base layer of powerstretch underneath the jacket, and the mesh panels tend to rough up the shoulder-tops on my smooth-faced baselayers.
2) collar height: I'm a total high-collar fanatic, so my base & mid-layers already provide 2.5-3.5" of neck coverage. (Mtn.Hardwear Powerstretch Zip & Cloudveil Wister are my faves)
I'm totally satisfied with the Koven Plus' collar height, even as a taller guy w/ longer extremeties.
3) the hood: *just* covers my medium Smith Variant helmet, which is a pretty low-profile lid. Leaves very little room to spare, I don't find skiing with the hood on comfortable, and my helmet has closable vents, so I've only used the hood on the lift in the midst of heavy & wet blizzard conditions.
4) pockets: hip pocket position is good, even w/ a pack, but they bonded in the powderskirt right beneath the bottom of the zipper, so there's barely 1/2 of "drop" at the bottom of the pocket to keep stuff from falling out. I keep valuables (cell phone & sports wallet) in the excellent chest pockets, and just use the hip pockets for stuff I'm prepared to replace (cliff bars, kleenex...).
The arm pocket really is silly. Maybe it could hold an RF lift ticket, or recco reflector, but I don't find it comfortable for even a single car key, so I don't use it.
Bottom line: I don't know if I'll still be shoveling snow in this 20 years from now like I am with my 1989 N.Face Mountain Jacket, but it sure breathes, moves, & feels better than any hardshell I've ever had!
