The sides feature flexible splints that protect against damage to your collateral ligaments without completely restricting your mobility.
The white straps are for locking the knee against anterior and posterior instability, for example, if you have loose anterior or posterior cruciate ligaments; or if you feel you don't have full control over your knee.
Finally, there is an opening for the kneecap, and a silicone elevation around it, so that it protects the kneecap in case of a fall, which is, for instance, good for handball/volleyball.
The material is 90% neoprene and 10% nylon. The product can be hand washed.
