Protect.CO Knee Brace

Soft Functional Knee Brace for Hyperextension, Mild-to-Moderate Instability, and Daily Knee Protection

 

The Protect.CO fills a specific gap in the knee brace lineup: a soft-frame functional brace that limits hyperextension and provides good lateral stability without the rigidity and bulk of a full aluminum frame brace. Long side bars made from breathable D-tex fabric extend above and below the knee, providing structural resistance to end-range extension and medial-lateral forces that cause pain in mildly unstable and hyperextension-prone knees. More structure than a neoprene brace. More wearable than a rigid frame.

Product Details

Support Level: Moderate-Maximum

Best For:

•       Knee hyperextension injuries — preventing the knee from extending too far back

•       Mild-to-moderate knee ligament instability

•       Daily knee protection during activity for chronically unstable or hypermobile knees

•       Active adults needing functional knee control without a rigid frame brace

•       Occupational knee protection in physically demanding jobs

Why the Protect.CO Knee Brace Works

Long Side Bars — Extended Structural Coverage

Side bars run significantly higher above and lower below the joint line than standard braces — providing a longer lever arm that more effectively resists the forces acting on the knee from above and below. Better mechanical control with less force required at the contact points, which means more comfort and less restriction.

Hyperextension Control Built into the Hinge

The hinge design includes built-in extension limiting that prevents the knee from extending beyond the anatomically safe range — the core function needed for hyperextension injuries and hypermobile knees that routinely bend backward beyond neutral.

D-tex Breathable Fabric — Functional Without Heat

The side bars and main body use D-tex fabric — a breathable material that wicks moisture and allows airflow, unlike neoprene that retains heat. The brace can be worn during activity without overheating, which makes neoprene functional braces uncomfortable for long periods.

Popliteal Mesh Panel for Behind-Knee Comfort

An open mesh panel at the back of the knee prevents bunching, pressure buildup, and heat retention in the popliteal fossa — the area where most braces cause discomfort during extended wear.

Built for Your Active Life

Ideal activities while wearing:

•       Daily activity and walking with a hyperextension-prone or mildly unstable knee

•       Golf, hiking, and recreational sport with a knee that needs functional protection

•       Physical work requiring all-day knee support without a cumbersome rigid brace

•       Physical therapy exercises where hyperextension limitation is clinically indicated

•       Any activity where the knee routinely extends too far and needs soft end-range control

 

For severe ligament instability requiring maximum structural control — particularly ACL/PCL tears — the Protect.4 Evo provides greater mechanical resistance. The Protect.CO is best for mild-to-moderate instability and hyperextension management.

Is the Protect.CO Knee Brace Right for You?

This might be the right brace for you if:

•       Your knee hyperextends during activity, and you need a brace that stops it

•       You have mild-to-moderate knee instability that makes activity feel unsafe

•       Neoprene braces haven't provided enough structural knee control

•       You need functional knee protection that's breathable enough to wear through a full workday
