Model number unknown. It wasn't listed on the jacket. The size is 3XL in Japan size and XXL in Euro size. It's an old jacket, but I rarely ride a motorcycle in the winter, and I've only worn it a few times. It has been stored in a place away from sunlight, so the condition is good. There is no deterioration in the reflective piping, which is common in this type of jacket. Also, the pocket zippers are water-resistant zippers, but there is no visible deterioration. It's a winter jacket with a slightly longer length, so it has excellent heat retention. The inner lining can also be removed, allowing for temperature adjustment. It uses Drymaster, so it has high waterproof performance and breathability to prevent stuffiness. Protectors are included in the back, shoulders, and elbows. As with motorcycle jackets in general, this jacket has higher heat retention than regular jackets, so it is a bit heavy. Because it has protectors, it cannot be folded up small. It may not be possible to send it via Yu-Pack, in which case it will be shipped by courier. ※ Search terms RS Taichi, Drymaster, motorcycle jacket, winter jacket, waterproof and breathable, cold weather jacket, RS Taichi, Manufacturer...RS Taichi Type...Motorcycle jacket Gender...Men's
