okay, well i would give this jacket 5 stars except for one major thing. But before that let me talk about the pro's of the jacket. The conduit sl material lives up to the reputation of being wind and water resistant. Keep in mind that this is no gor-tex pro and should not be used as so. 650 fill is adequate for the most extreme weather that marquette mi can offer, including temps in the -15's with windchills of up to -30 or 40. The hood is well designed, and unlike the parka it zips on and off which makes it better. the cinched waste does not compare to a powder skirt, but it is not supposed to.This jacket is not made for those deep pow pow days. The double zip feature is perfect because it is very convenient for belaying.And now to the MAJOR con. The zipper of this jacket is extremely frustrating. I have talked to a local shop owner who has reported numerous sub zero sl jackets being warrantied for faulty zippers.My jacket somehow got zipped up unevenly and jammed. when i went to unzip the jacket i blew out 3 teeth on the left side of the jacket. luckily it was near the bottom and i can still wear it for now. these blown out teeth are a major problem though. Backcountry has awesome customer service and will replace this zipper at with no problems, but still, come on? For close to 300 dollars quality should not even be an issue. By all means, buy this jacket, but beware of major zipper issues. They are prevalent and will ruin your day.
