Hit-Air Airbag Vest for Horseback Riding and Motorcycling - Size S Price is not negotiable. This is a Hit-Air airbag vest. Retail price: Approximately 48,000 yen Used approximately 60 times since purchase. Purchased last May. This is a USED item, so please purchase a new one at a store if you are concerned about even minor details. It was used by a child, so it has been handled roughly and has some mud splatters. While there are many Hit-Air protector vests for sale, the airbag tube (image 4) deteriorates over time (approximately 4-5 years) and may not deploy in an emergency. This can lead to serious injury, so we recommend a newer model. The airbag tube can be replaced about 4 years after the initial purchase at the Hit-Air manufacturer's headquarters in Nagoya or at the place of purchase. For safety reasons, we recommend replacing the airbag tube of older Hit-Air protector vests. This is different from the gas cylinder.
