The Mystic in Blazing Yellow is the best shell I've ever used. For boarders or skiers who want a bit more style, the jacket is great! I'm 5'7", 140lbs, with a 38" chest, and the Small fits perfectly. The arms are the right length, and the jacket still has a baggy fit (but not too much so).
Both shadow and blazing yellow jackets have a detailed pattern that looks kind-of like scratches from up close--the jackets are not just straight-up gray or yellow. Other than that, the jacket's description is very accurate.
Complaints: The shell does not really fit my Giro Omen helmet that well. With the hood over my helmet, the jacket is pulled up and I cannot zip it up all the way without squishing my nose.
It's definitely heavier than other shells, but the jacket performs well in the powder and features good breathe-ability when the vents are open. The workmanship is high quality. The yellow won't get you lost in snow, but may get you noticed by some ski bunnies.
I'm looking forward to see how the matching Mystic Pants interface with this jacket, but I'll review those after they get in and I get back from Vail.
