Not as stiff as the C-Frame, but a good chassis made from glass-filled nylon for comfort and a Carbon Injected knee for that rigidity, which reduces the ACL, Meniscus, and MCL injury risk. The Z-Frame is also CE certified as a medical device and as impact protection.
A great alternative knee brace with a single sided hinge is the C-Frame Junior.
