There is no better lightweight GoreTex jacket on the market. You get full Goretex Pro protection in a minimal and sleek package. I use this for everything; hiking, fly fishing, climbing, splitboarding, and mountaineering. It has withstood deluges of rain, horrible blizzards, and been with me to the summits of several mountains.
The fit is a bit unique but not unlike the rest of the Alpha series, although the torso fits a bit more slim. Don't worry about not having pitzips, you don't need them. I regularly wear this on the skin track up and it breathes just fine. For the price I cannot find a better jacket and have tried many. Be aware that it is not cut for the ski resort, but if you need a four season jacket for every type of alpine adventure this is the ticket.
