Our lightweight running jacket is made for performance so it’s wind resistant, with a funnel neck collar to stop the wind whistling down your neck and a back vent with mesh fabric lining from the vent to the hem for ventilation. ​It has a half zip so you can drop heat quickly and a ribbed cuff for a comfortable fit. ​. . The dipped back hem has an adjustable cord and toggle so you can draw it in to your waist and the zipped hip pockets have a practical carabiner. ​And it all packs into its own back pocket. But it’s hard to run in our great outdoors and not care deeply about the planet. ​. . That’s why this jacket is 100% circular. We’ve worked with recycling processor Project Plan B so before we even made this jacket that we knew how it would be 100% recycled. 73% of clothing ends up in landfill or incinerated. This jacket never will. And no matter how far you run, this jacket leaves no carbon footprint.. . Main Fabric: 100% recycled polyester
