i bought the saga zipster hoodie in XL and im quite pleased with it so far. The material seems good and the fit is excellent, im 6 feet tall and it sits about 3-4 inches north of the knee. It can be worn in public without being ridiculous and will still be big enough to ski in. i cant say anything about actual ski-ability (ie, waterproofing) as i have yet to ski in it, but overall it was a good buy for me.
hope this helps
