Having used an Arcteryx Beta AR shell for many many years, I got one of these 2 years ago as a replacement..mainly because the older jackets hood did not fit my helmet well. This jacket is lighter and has been an excellent ski jacket. Easy to layer under, light, bombproof as far as wind/snow...and even rain....and although some don't like the collar/hood, I always zip it all the way up and the collar sits in front of your chin and does not flap around. The hood works well with ski/climbing helmets.
I'm 5'11'' and 180 lbs...went with a large cause I wanted room to layer. The M was a little tight across the upper back/shoulders.
