The Vortex Jacket is a 10.5oz brushed flannel outer with a low-pile sherpa collar and full sherpa body lining for real warmth without the bulk. Sleeves are lined in smooth taffeta so you can slide it on easy over a hoodie or tee. The stripe pattern keeps it classic, while snap closures, welt pockets, and a clean Sullen label finish it off. A heavy, everyday jacket made to hold up wherever the season takes you.
