Fits my 13-year-old daughter. She weighs 105 lbs with slim legs. I tried it on as well and I weigh 125 lbs. On me, the top garter strap was tight above my knee. But the garter strap below the knee was fine. Elbow pads fit fine. Also, DO NOT TEAR the mesh bag that it comes in. I almost made the mistake. The top part of the black mesh bag has a draw string. So you use the mesh bag as the storage bag for the pads.
