Like New! ❣ For Horseback Riding & Motorcycle Use MUGEN DENKO hit-air Airbag Vest L Price is firm. This is a MUGEN DENKO hit-air airbag vest. Retail price: Approximately 52,000 yen Used approximately 15 times since purchase. Purchased in June of this year. This is a USED item, so please purchase a new one at a store if you are concerned about even minor details. There is a name written on the inside. There are many hit-air protector vests for sale, but after a few years (about 4-5 years), the airbag tube (image 4) deteriorates and may not deploy in an emergency. This can lead to serious injury, so we recommend a newer model. The airbag tube should be replaced about 4 years after the initial purchase. You can have it replaced 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. By the way, it's different from the gas cylinder.
