This is the Patagonia Men's Airshed Pro Pullover. I've worn it a couple of times in the winter, but I'm selling it because I don't feel I need it. To be honest, it's hard to find the right time to wear it. Even in winter, I can manage with a T-shirt and arm warmers, and if it gets cold, I can just throw on a Houdini. As this is a used item, I will only accept transactions on a no-claims, no-returns basis.
