Underground C1 Loop Puffer Jacket

8 items left!

Our warmest, heaviest, and most premium jacket ever. The Underground C1 Loop Puffer is built for the coldest of conditions and will keep you cozy no matter the situation. The outer is a tough, tear-resistant fabric and much stronger than other puffer jackets you would find on the market. The detachable hoodie allows the jacket to be converted into a stylish bomber jacket with one simple zip.

The jacket features lots of extra detailing including HardTuned branded zips, embroidered outer printing, and a huge inner geographical print of Tokyo Bay; highlighting the C1 Loop.
