Made with function and convenience in mind, the Norse Projects Thorsten Packable Shirt Jacket is an ideal travel companion. It's constructed from 85 GSM nylon that provides lightweight durability when on the trails, while a mesh vent panel on the back gives the piece breathability in warmer temperatures. When in transit, the jacket packs into the chest pocket for compact storage in backpacks and luggage. The piece is finished with a polyester lining and snap front closures.
