I've just bought one of these (bargain from Ebay from a guy who won one and didn't want it!) and it's superb. Very lightweight and breathable and a decent fit. I'm 5' 10" and pretty slim so the medium is perfect. I'm a big fan of smocks. I do a lot of running and cycling and it's greatfor this. The Maya blue is really nice too.
From experience I have found that Event isn't the most hardwearing so for my winter hardshell I always opt for Goretex proshell. But for a light shell like the demand which won't be used for hardcore stuff, Event is ideal.
