This jacket is the best ski jacket, and possibly best purchase i have ever made.
The 20K/20K waterproofing has made this jacket a pleasure to own, as no matter how much soggy snow you fall into, this will keep you dry as a bone.
The insulation of this jacket is supreme, and I have sat in chairlifts, in the Alps, in blizzards with only a baselayer underneath, while being toasty warm. And i am not a warm individual.
The excess of pockets makes this jacket perfect for skiing and outdoor activities, as there is no such thing as too many pockets. The ski pass sleeve pocket is a great position, as is the clever addition of an inbuilt goggle wipe.
I have had this jacket for atleast 2 years now and it still going strong, looking stylish and upmarket on and off the slopes.
The detachable hood makes it versatile, and the fact that the hood is insulated is a large point in its favour, as many jackets scrimp on hood warmth.
Skiing specific features on the jacket include a good snow skirt, with my only complaint being it is a little looser than it should be. The extra high collar is possibly my favourite aspect of this jacket, making scarves almost unnecessary, and hiding your face in grim weather easy.
Sizing is as stated, and my size small is perfect for me ( a size 8-10 ). Having said that, the slightly 'snowboarder-y' style of it is a little baggy on my frame, but adds to the comfort when skiing all day.
Finally, this is top knotch. I hope to buy another one in the next decade when my current one dies. Worried about the price? It was worth it for the awesome performance and tech.
