What is OS1ST?
Among the many supporters, it is a supporter used to suppress movement so that it does not overload the recurrence instead of the acute phase. Unlike fixed orthotics that are firmly fixed during the acute phase, it is hard to get stuffy, easy to move, and convenient to carry. It is a brand that is classified as a supporter category called NEXT TO SKIN and boasts the No.1.

PS3 is an effective supporter for patella tendonitis (primarily pain under the knee: jumper knee).
The cause of the so -called knee pain is that the patella (knee plate) is pulled upward due to the use of the hip joint and the quadrice muscles (front thighs on the front side), causing muscles to be pulled upwards. Inflammation occurs, causing pain.
Some people usually hurt, but especially those who climb the mountain will put a heavy burden on the quadriceps muscles when descending. Before that happens, installing a PS3 supporter, which has little excessive movement, has the effect of preventing the knee plate and patella tendon from being pulled and suppressing (delaying) pain on the disease.

size
There is a size chart in the image. Let's measure the size under the knee and choose.
If you have a thin woman and a man's legs, it will generally be M, male ordinary people are M, and those who are obviously thicker than the general public will choose L.

The manager of the store manager
There are many customers who are worried and become unable to enjoy the mountain trip once the knee starts to pain, so if you are likely to have pain, keep it in a bag instead of a charm. "If you are prepared, you don't have to worry about it."
