I got the Cold Fusion Jacket with an attached hood, pit-zips, and loads of pockets two years ago and have used it as my main shell for resort skiing ever since. The only time I don't wear it is if heavy rain is a possibility, since all those untaped seams and zippers would probably leak. The WB400 fabric is stretchy, quiet, windproof, durable, and surprisingly breathable. The quality of construction is good and I have had no failed seams or tears after 35+ days of use, including a lot of tree skiing. The fleece lining is warm and comfortable on bare arms so for spring skiing I wear just a thin t-shirt underneath.
The jacket doesn't have a powder skirt but the hem drawstring (in a 1" supplex channel) seals pretty well. I specified a medium torso length which works fine with my high waisted ski pants. But I wish I had added a couple more inches to the torso for when I wear short waisted lightweight pants in the spring.
I got my jacket before the water resistant zipper option was available. But I like how easy it is to pull the pit-zips and main zipper open, while some water resistant zippers can be sticky. The cuffs are non-adjustable elastic, which work fine with my cold weather gauntlet gloves. But I would prefer an adjustable cuff for ventilation and ease of fit with spring gloves in warmer weather.
