An adjustable knee brace with an open kneecap and reinforced side supports. Upper and lower wrap straps fasten around the leg, so you can set the fit yourself. Sold as one brace.
Good for: wearing on walks, in the garden and through everyday chores, when you want a brace you can tighten or loosen yourself.
Not made for: guessing your size. The fit depends on your thigh measurement, so measure first. Ask your doctor or physiotherapist if you're not sure it's right for you.
Measure around your thigh 6 in (15 cm) above the kneecap and choose the size in the size guide. Put the brace on with the kneecap in the opening, then fasten the upper and lower straps until the brace feels snug but comfortable.
