MMA Knee Guards That Lock the Kneecap in Place
At ONX Sports, our mission is to protect the athlete — and the partner across from them. The ONX Premium Line knee guard is designed to lock the kneecap in place so the pad does not slide during use.
With a depth of two inches, the pad keeps the kneecap from touching the material, preventing bone-to-pad contact and making the equipment safer for an opponent. Multi-layer ONX foam disperses impact to reduce direct force on the joint.
Trevor Wittman, the mastermind behind the ONX patented technology, has spent the last 10 years designing and testing the next generation of MMA protective equipment.
Sold as a left and right pair. Shin guards are sold separately — or get both in the MMA Shin & Knee Guards Bundle.
Knee Guard Sizing: Small or Medium shin guard → SM/MED knee guard. Large or X-Large shin guard → L/XL knee guard.
