I bought this recently, and have been really impressed by it. It saves weight where it should; the new mountain fit(2013) that Mountain Equipment have developed is a big improvement on their old cut and probably saves weight; it won't ride up when you raise your arms, it's long enough to protect your mid-drift and is a better fit across the abdominal area(less baggy). It doesn't,however, compromise by cutting material in a race to defy gravity in other important areas. I think a Mountain Jacket without a storm flap over the front zip is pure folly; a lot of waterproofs dispense with a flap now, and reassure you with "laser cut and bonded" and "developed by people with enormous brains as part of leading space age technology" etc. Believe me, you're better off with a storm flap for durability and security,particularly if you're using it year round and in driving rain. The hood is also fabulous; it won't flatten in high winds because it has a wire brim....don't underestimate the importance of this. It's also well designed so it'll hug your head with or without a helmet on and gives great visibility.I thought initially that the new 3 layer Gore-Tex Pro was an attempt to get you to unnecessarily buy the latest material.I was sceptical of how noticeable the extra breathability would be in real terms. There is , however, a noticeable improvement. To give you an idea, I'm happy to run in this, and it feels as good as my Gore Active Shell, which is designed for high aerobic activity.My old Gore-Tex was useless to run in;you'd just get too hot. All round, a really great jacket. Get one.
