This mesh, zip-up jacket from Y-3 is pretty practical as far as $320 windbreakers go. I mean, there's only 3 weeks a year that a lightweight jacket actually makes sense to wear as your outermost layer, but if you live somewhere that's always 60 degrees, then this is pretty much perfect. Really the only place I know like that is San Francisco, so ATTENTION SAN FRANCISCO: COP THIS GARMENT. IT IS REALLY QUITE NICE. Wear it while you ride the trolley and eat burritos and think you're superior to people that live in New York. It also reverses to a dope ass tie dye print, which means it will take people a little longer to catch onto the fact that you're wearing the same alphet every single day.
