- the clothing body 30 and the impact-absorbing member 1 b are fixed to each other by the binding member 20 .
- the length of the impact-absorbing member 1 b is longer than the length of the clothing body 30 . That is, the impact-absorbing member 1 b is loosely fixed to the clothing body 30 by the binding member 20 . In this way, flexibility of the protective clothing 2 is further enhanced.
