"Performs really well in a Mountaineering environment"
Just came back from 3 weeks in the Italian Dolomites and used this shirt almost every day. Hiking and climbing on hot steamy days, cool days, rain, snow or hail, this shirt kept me comfortable and dry. Even when sweaty-wet, it felt dry. Washing is very simple, a quick wash in powder in the hotel sink, 2 rinses and laid out for 3 hours, and that's it. I used it three days running (each a 3-4000ft hike) without washing and there was no detectable smell. I'm back home, put it through the machine wash, hung up to dry and it looks like new. I had a backpack on every day, and occasionally a climbing harness, and there are no signs of wear. A really great performing shirt, and very comfortable to wear.
