What is NOT a requirement for t-shirts used in competition?

In powerlifting competitions, specific guidelines are established regarding the attire to ensure fairness and adherence to the sport's standards. T-shirts worn during competition play a significant role in this.

The statement regarding the material being rubberized is not a requirement for competition t-shirts. Instead, the governing bodies have set rules primarily focusing on functionality and uniformity rather than the specific type of fabric, as long as it meets general quality standards for athletic wear. Thus, a t-shirt made from rubberized material could fall outside the realm of acceptable due to potential implications on performance and safety, but there is no outright prohibition against this type of material. The other aspects mentioned, such as the prohibition of seams, pockets, or buttons, emphasize a standard design to minimize advantages and ensure uniformity among competitors. Form-fitting styles are required to ensure that the garment does not interfere with the lifting mechanics, and regulated sleeve lengths help to maintain a standardized appearance among lifters.
