KneeCaps are specifically designed to provide compression, warmth and lateral stability when performing functional movements such as Dead lifts, pistols and squats. Unlike other supports, Knee Caps are "extra tall" and designed to compress the VMO* at its insertion point above the patella to help ensure proper stability and tracking. Knee Caps also provide compression and warmth to promote blood flow. • Added height for VMO* support • Available in 5mm or 7mm neoprene thicknesses • Sold as pair 5mm vs. 7mm The difference between the two is support.

It is located on the inner part of the front of the thigh. The lowest part of the vastus medialis, called the vastus medialis oblique (VMO), achieves its maximum contraction during full extension. The VMO helps to stabilize the patella and allow it to track properly.
