2-Piece Knee Support for Sports, Summer Use, Knee Stabilization, Sweat-Absorbent and Quick-Drying, Perforated Design, Adjustable 【Special Springs】Strong, with three Velcro straps firmly securing the support at five points. There is no constriction, and it feels like a single unit. Furthermore, the back is non-slip, so it won't slip even during intense exercise. You can easily put it on by wrapping the support around your knee and securing it with the Velcro straps. This is a free-size product that can be used on either the left or right knee, and can be used by people of all genders and ages. 【Support Feel】We have strived to further improve the support, and have achieved a wrapping support feel by securing five points with Velcro straps. 【Knee Protection】Special shock-absorbing material is used in the center hole, so you can rest assured that it will absorb impact even if you land on your knee. It disperses pressure on the knee and also helps with meniscus recovery! 【Elasticity & Breathability】It has excellent elasticity and is highly breathable with a structure that has countless holes to prevent sweat from getting trapped. 【Great Performance】The design allows for the support to be put on either the top or bottom, so it can be worn on either the left or right knee. It adheres with durable, strong Velcro straps, and can be adjusted for larger sizes, so it can be worn by both men and women.
