・ This is an Iron Heart PrimaLoft down jacket (https://ironheart.shop-pro.jp/?pid=174966434). I purchased it for 100,000 yen a few years ago, but I'm selling it in excellent condition with only a few uses because I prefer to wear another Iron Heart jacket. (The tags have been removed.) ・ The size is S, and the actual measurements are: shoulder width 40cm, body width 50cm, sleeve length 68cm, and length 73cm. It fits perfectly with a long-sleeved T-shirt and thermal layer for someone 173cm tall and weighing 70kg, and it's warm enough. ・ This is the ultimate down jacket, offering the best of both worlds: 60/40 (Rokuyon cloth) material that blocks wind and repels rain, perfect for riding a motorcycle in mid-winter, and the insulation of PrimaLoft, an advanced synthetic fiber. ・ I tried on a West Ride racing down jacket, a staple for Harley riders, but it was too tight and difficult to put on and take off, and I was worried about tearing the clothes. This product, however, is very durable and can be worn without any concerns. ・ It's in very good condition with only a few uses. I don't smoke, and it has been stored in a well-ventilated indoor area.
