This is the best backcountry snowboarding jacket I've owned to date. The Gore-tex pro-shell and zippers are bomb-proof. The fit is perfect and the jacket looks awesome. The only thing that I don't like is the size of the hood (it's on the small side) but if you size up it's not as much an issue. I'm 5'10" 165lbs and a size small fits perfectly with enough room to layer. Go up in size if you like a baggier fit.
You really can't go wrong with AK. The higher price-point fabric is definitely worth it. This is an excellent jacket that's worth the money.
