In reply to haydn:
I recently bought the ME Fitzroy jacket after reading many positive reviews on here. I have to confess that I haven't used it out on the hill yet due to the crappy travelling situation over the last few weeks, but it's kept me warm walking round town in -10 C and near blizzard conditions so far. In my opinion it's just very well thought out, hood design seems great, cut is good etc.
I tried a Rab Generator Alpine on as well when I was shopping, but wasn't as impressed with it. The main thing that put me off it was the 2 way waterproof zip, which not only was trickier to do up even in the shop, but in my mind, pointless. The jacket isn't fully waterproof, so why put a waterproof zip on it? Overall it just didn't feel as good quality as the Fitzroy, and this is coming from someone who is more than happy with other Rab products.
