On Running Zero Jacket (Men's) - White/Meadow

Technology
Works like magic The only reason you know you're wearing this featherlight jacket is the protection you get from wind and rain. How? Mini-ripstop, a protective fabric that weighs just 29g per square meter ("lightweight" tees usually start at 160g). So nothing holds you back – whatever the weather.

Materials
Beat the elements Fully windproof and water-resistant, you can run, hike and cycle through gales and light rain without feeling the chill. Ventilated underarms keep you airy and dry as you work up a sweat. And it's made from recycled polyamide. Works for the planet works for you.

Design
Smart cookie Zero by name, zero by nature. Folding away into the tiniest of pockets, it's easy to pack – whether you're trail running, hitting the gym or need an extra layer for a late-night jog. The reflective On logo on the elbows keeps you visible to passers-by long after the sun's set.
