Patagonia Airshed Pullover
“For weather protection without the unwanted sauna treatment, the stretchy, breathable Airshed Pullover slides over your baselayer to provide just the right warmth and wind resistance while you’re on the move. Built with the same shell material as our revolutionary Nano-Air® Jacket, it’s a whisper-light soft-shell pullover perfect for mountain biking or trail running in changeable weather. ”
weight 3.7 ounces
I will hold off until they make a hooded version, but this has me excited. Similar weight to the houdini but better suited to high exertion. I’ve been using a black diamond alpine start which is twice the weight.
