Which of the following is not permitted alongside knee wraps during competitions?

During competitions, athletes are allowed to use various pieces of supportive equipment designed to enhance performance and safety. However, knee wraps and knee sleeves serve similar functions in providing support to the knee joint. Wearing them together can result in an unfair advantage, as the combination may provide excessive support beyond the intended limits set by powerlifting regulations.

Knee wraps are designed to offer compression and stability to the knee during squats, while knee sleeves also provide support but are generally less rigid than wraps. Therefore, the rules specify that only one type of knee support is permitted at a time, and since knee sleeves are a direct alternative to knee wraps, using them simultaneously is not allowed.

On the other hand, squat suits, weightlifting belts, and wrist wraps serve different purposes and focus on other body areas. Squat suits provide support to the hips and legs, weightlifting belts stabilize the core and lower back, and wrist wraps assist with wrist support during lifts. These items can be used in conjunction without violating any competition rules, which is why they are permitted alongside knee wraps.
