About a year ago I finally decided to dig my pockets deep enough to dish out cash to purchase "Mountain Hardwear Transition Featherweight Zip T", lightweight, yet windproof shirt made of Gore-tex Windstopper Next2Skin (N2S). After using it in rock climbing and trail running, I can't rave enough about it. Why more manufacturers don't make apparel like this, is beyond me.
Windstopper N2S is typically far thinner than (most) softshell fabrics, thus it breathes better, packs smaller and is not too hot. In my book, you can't find a better clothing for summertime rock climbing in alpine surroundings or otherwise chillier days. Granted, these things don't come cheap, but they are worth every hard-earned cent.
Few year back I decided to replace my old and reliable bombproof Marmot Alpinist jacket with new hardshell. Finally I decided on Mountain Equipment Matrix, basically a Paclite shell with reinforcements of Gore-tex XCR. After experiencing its greatly enhanced breathability, reduced weight and bulk through simpler design, I doubt I'll ever go back to full-on armour-like shells. Granted, these things aren't as durable (which I experienced first hand by tearing mine with an ice axe pick during one less controlled slide during a walk-out). That being said, very few fabrics are particularly resistant against well-sharpened picks. Furthermore, light weight shells are also so much cheaper that I feel somewhat reduced longevity is justifiable for getting better function and added comfort.
