Every cyclist should own at least on packable shell and this is one of the best out there thanks to quality materials, design and construction. The Gore Bike Wear Xenon 2.0 Active Shell Jacket is a very lightweight and packable jacket that offers wind protection and water resistance with an ergonomic fit. This jacket folds to a size that can easily fit in a standard jersey pocket. The Xenon 2.0 AS jacket has all season versatility but might be slightly too warm in summery weather.
Gore's windproof and water-resistant Windstopper Active Shell fabric makes the Xenon 2.0 AS surprisingly breathable for an unventilated jacket. A form fitting cut with mesh lined sleeve and back panels virtually eliminate billowing that can occur with other shells. Other details include a longer back and thin neoprene cuffs that seal and streamline the glove and sleeve interface. There are zipper garages on both the top and bottom and there is even a leather grip section to hold while you are unzipping.
This is a awesome jacket! Blocks the wind very well, with minimal flapping in the shoulder area. I usually wear a large and in this jacket a large fits me real tight through the chest and stomach. I'm 6ft and 160lb. It is very comfortable in the riding position. If you are in doubt about your size, I recommend size up.
Pros: Very Packable form fit and excellent protection
Cons: A liitle hard to take on and off
