Patagonia Airshed Pro Pullover - Women's
This layer is stretchy, lightweight and fast drying. I really like where they put the super soft, stretchy material: arms and hood. It makes it way easier to put the hood up comfortably and if it’s down, you hardly notice it. For the arms, you can scrunch them up comfortably and they’ll stay put.
It’s packable too!! It folds into a small stuff sack near the hood.
I have worn this layer running and bike touring across Europe. I wore the hood up in the evenings and it fit perfectly under my helmet.
