Awesome, but not for rock climbing !!
No negatives about this jacket. It is small, lightweight, warm enough, water resistant .... but not for rock climbing. I went climbing at Vantage this weekend and it was pretty chilly and windy on Sunday morning. So, I put on this jacket and it did keep me warm. But the downside was that it got buffed up from the winds and was bulging at the stomach so much that I couldn't see my footholds down. It was really annoying on the overhanging routes not be sure of where your foot is. I am 5'11 and 160 lbs and got a medium. I am gonna return this and may be try the patagonia jackets.
