What are knee sleeve specifications regarding additional support?

Knee sleeves used in powerlifting are intended to provide warmth and support to the knee joint without offering rigid stabilization or mechanical advantage. The specifications focus on ensuring that the sleeves maintain a level of flexibility necessary for optimal performance while still providing some degree of compression and support.

The guideline that no additional support is allowed ensures that the sleeves do not enhance performance beyond the natural capabilities of the athlete. This maintains fairness in competition, as excessive support could provide an unfair advantage while lifting.

Other specifications, such as double ply neoprene or having ventilation holes, do not directly speak to the element of added support. Therefore, option B aligns perfectly with the principles established for the use of knee sleeves in sanctioned lifts, ensuring that they serve their purpose without giving an undue benefit to the lifter.
