thanks for the fit suggestions. I went yesterday to my local ski shop and they also pointed me towards Arcteryx for a slim fit, or is it jsut that the margins on this brand are the highest?
by sheer fluke, on my way out I ended up talking to the staff member doing all the product training instore, he spent the last couple of seasons at Whistler. he has a dryskin xtreme Cloudveil esoftshell which he thinks is the most breathable (great for ski touring, uphill) but too draughty on the downhills, he needs to put on a hardshell on descents. for better wind resistance and warmth he recommends PowerShield.
btw the Arcterys Gamma Hoody has a longer torso cut this year and uses Gore tex XCR in the shoulders and arms, PowerShield anywhere else. They are not allowed to mention the XCR bit b/c the jacket is not 100% waterproof!
