I'm really interested in this. I was about to buy a Gore Phantom, for the three seasons flexibility of the removable sleeves. So is this jacket more of a waterproof and the Phantom more a windproof?
Also on sizing, I've checked on the Gore website, used their 'Trufit' calculator, and it says I'm a large, though everybody seems to say order a size up. I wouldn't really be layering up under this, only one layer anyway.
