After some brutal, covert interrogations, we discovered the jacket in question is part of the Spring/Summer collection for Y-3, Adidas's high-style brand designed by Yohji Yamamoto. According to our sources at the label, the slim-cut zip up is cut from lightweight cotton (but apparently, is not bullet-proof) and will be available in stores shortly after the new year. While they refused to talk price, we'd estimate it to be in the $400 to $500 range based on their current price-points. Godspeed, sir. Available at Y-3 on January 15th, by calling 917.546.8677.
