I got one of these in the sale just after Christmas, been very impressed with it so far, it's my first return to Goretex for years as my last couple of jackets have been eVent. like you say it's surprisingly light (although not as light as my old SuperDru) but offers lots of nice touches, great protection and amazing build quality...oh and some rather nice bright colours too...ive got the glow one with the blue zips.
I was a little worried about the pit zips and noticing them when wearing short sleeved baselayers underneath and their general flexibility but so far so good, most of the time i've not noticed they were there.
I have a covert that i got in the sale...infact i have two one is the cardigan type, both were half price and they are toasty warm but ive never worn either on the hill.
i also have a berghaus smoulder hoody which is fantastic, its thin, warm and has a brilliant ninja style hood, fits over a base layer and under just about all my other gear....its been a constant companion over the last year or so.
