What is the restriction for knee sleeves in relation to the singlet?

Knee sleeves cannot touch the singlet due to specifications established in powerlifting regulations aimed at standardizing equipment use and ensuring fair competition. This rule is in place to prevent any potential advantage that could be gained through clothing interactions during the lift. Maintaining strict boundaries regarding the contact between specific items of apparel, such as knee sleeves and the singlet, helps uphold the integrity of the sport by ensuring that the equipment used does not interfere with the official lifting attire.

Other options suggest either acceptable interactions between the knee sleeves and the singlet or allow for different configurations, which would not align with the guidelines that facilitate uniformity and clarity in competition. By enforcing the rule that knee sleeves cannot touch the singlet, officials can better monitor compliance and ensure that all lifters adhere to the same standards.
