BSN Jobst Safe-T-Sport Wrap-Around Hinged Knee Brace Large, Black, Neoprene, 18" to 19" Circumference.

Front wrap closures for quick, easy application - especially easy to apply over tender or swollen knees.
Medial/lateral metal hinges allow for full flexion and prevent hyperextension.
Open behind the knee to help prevent bunching and improve comfort.
