Fully-Featured Hardshell? This one!
I'm not usually a big fan of GORE TEX, but the axiom is the lightest, stretchiest, and most breathable GORE waterproof shell I've ever used. I've even kept it on for long ski touring climbs amid stormy weather, and managed to have it stretch with my movements and get breathability that far exceeded any other GORE shell I've used before. I don't know how it stretches like it does, but this definitely allows it to move with you as you hike or climb.
