I bought it after a fall accident in Motorcycle.
I knocked my knees at the time of the accident, but it was a bruise but I could not move for a while with pain, and I got help from the surroundings.
I struck my knees, shoulder, palm and the ground, but the knee pain is a half endless.
I have never fallen since I started wearing it, but there is a sense of security by wearing it.
Since there is a switch at the knee, when you are riding a Motorcycle, there is no uncomfortable feeling or discomfort when you are taking.
Size is "Kids" And I think that it is possible to use it for the person who is small and the woman of the body.
Since Belt is also fixed with 3 pieces, I am using it and I do not have Gap at the moment.
