Size is L. Sold as a set of left and right for 1980 yen!! With anti-slip function! These are high-quality knee sleeves made of neoprene material! I used them for a while when I had discomfort in my right knee, and they reduced the load of daily life without restricting my movement too much. My knee circumference is 33cm. Please refer to the slide for a size guide. I found that the M size provided a moderate compression and was easy to move in, which was just right for me. For reference! The L size was a little too big for me. - Type: Knee support - Size: L (set of left and right) - Thickness: 5/7mm - Material: Neoprene - Features: Non-slip technology, additional compression and support - Recommended height: 172cm - Recommended weight: 63kg Thank you for viewing.
