ZAMST JK-2 (Knee Support, Universal for Left and Right) Size L. I am selling it because I no longer have the opportunity to use it. The Velcro hold is not an issue, and the support functions perfectly. Please check the product condition in the photos. It has been cleaned before listing, so you can use it right away. 【For Troubles in Jump-Related Sports】 Supports knee problems in jump-related sports. The unique pad reduces the load on the knee during jumps. 【Accurate Compression with Unique Jumper's Pad】 Accurate compression with the unique two-layer Jumper's Pad reduces the burden on the lower knee. 【Easy Adjustment of Compression Force with Under Strap】 Compression force can be easily adjusted with the under strap. 【Achieves Comfortable Fit】 Power double russell, which has breathability and moderate compression, provides a comfortable fit and hold. Bending and extending the knee is smooth with little discomfort. 【Accurately Compresses Around the Patella】 The semi-circular patella pad gently and accurately compresses the patella, and together with the H-shaped Jumper's Pad below the knee, it enhances knee stability. Thank you for viewing.
