This is a high-grade ACL brace for the left knee (Size: small). Normal wear and tear from approximately 6-8 months of use, I am including a carrying bag, two calf cuffs, and a Donjoy under-brace neoprene sleeve. The padding for the frame is new (recently replaced). It is a very sturdy brace, and it can be used for contact sports. I am including the sizing chart directly from Donjoy. Here are their specs:

The Donjoy Legend SE-4 Knee Brace is a more affordable, economy model based on the same design as the traditional version. The Donjoy SE 4-point features the same tempered aircraft aluminum construction as the traditional Legend X but has lighter grade hinges without slide shield protection on the sides of the knee. The brace does not come with any accessories as mentioned below in our comparison analysis, and features a shorter warranty period. The Donjoy SE 4 Point Legend Knee Brace can be used for contact, as well as, non-contact sports protection, and has moldable thigh and lower leg cuffs to provide an excellent fit. It does not come with a flexion/extension stop kit for adjusting the range of motion of your knee and does not include a brace bag. The Donjoy SE-4 Legend knee brace is ideal for moderate to severe ACL or PCL injuries, MCL and LCL instabilities.
