Ty Nelsonwrote a review of Patagonia Airshed Pullover - Men's on February 9, 2017
This pullover seems like a jacket at first, but after wearing it last fall it has become my favorite long sleeve mountain bike jersey every. It's basically just a single layer of Nano Air shell fabric, without any insulation. Still has the DWR coating for wind and light protection from water, and a good amount of stretch to it. Fit for my sample was fairly slim, I still wore my regular medium size, but it was more comfortable with a short sleeve T underneath as opposed to long sleeve. Some people might be psyched if they size up depending on how slim of a fit they're looking for.
I use this as a complement to my Houdini, I always have one of them with me when I head out for a ride or run. The Airshed is really like a stretchy breathable counterpart to the Houdini, and it self stuffs into it's chest pocket for storage. I'll wear the Airshed for an entire ride, where the Houdini is usually used when the weather gets nasty, or for a chilly DH back to the car.
