I purchased this here, but I have only used it about 5 times. After that, it was professionally cleaned and inspected through Riding Club Crane. It is clean, as there is no sand or dust as mentioned in the previous listing. Below is the information from the previous listing. ↓ ……………………………………………… Hit-air hit-air Airbag Protector Air vest Color: Black Size: 2XL〜4XL Width: 110〜130 cm Height: 175〜195 cm Horseback riding Jumping Used about 3-5 times and stored at home. There is some sand and dust, but the condition is still good enough to wear. There is some slight wear on the string connected to the cylinder, which tends to rub. Please purchase if you understand that this is a used item. Since it comes with a cylinder, it cannot be shipped by air.
