The airbag tube is sandwiched between the shock absorbing pads, and the airbag and shock absorbing pads provide excellent shock absorbing performance. The simple structure of the H2 allows the airbag to inflate and deploy more smoothly. The harness-style design allows for a wide range of compatible sizes and the waist belt allows for size adjustment. It can be worn all year round, over both spring/summer and winter jackets.
