I've been using my Rab Myriad jacket extensively lately while back country skiing on Mt. Hood, Oregon. Is has performed well, fending off wind and snow and all the while not leaving me clammy with sweat. And I am a "sweater". The quality of construction is top notch and it is light weight. Making it a perfect back country skiing shell. I'm 6'-3"/190 and size large fits great. Arms are a little longish but overly so.
