Nice find. Also, no love for the pullover version? It's almost the same as the anorak, just minus hood, so a bit less weight/warmth and a lower price - $63.60:
I have the pullover in a medium, and it weighs 194g (6.84oz). With either model there is opportunity to shave a few extra grams off - you could remove part of the cuffs (they are rather long) and swap out the hem adjustment cord for something lighter.
I had almost bought the hooded version instead of the pullover, but I wasn't sure about how the hood performs in use. For those who own the anorak, how well does the hood work?
