What are the allowable materials for lifting suits and singlets?

The choice indicating that specific fabrics without additional supports are allowable for lifting suits and singlets is correct because it aligns with the regulations set by the International Powerlifting Federation (IPF). According to IPF rules, lifting suits and singlets must be made from materials that provide sufficient strength and support while ensuring safety and fairness in competition.

This means the materials should not have any additional supports such as padding or other enhancements that could provide an unfair advantage to the lifter. The emphasis is on the functional properties of the fabric itself and how it fits the athlete, ensuring that the equipment adheres to standardized guidelines. By allowing only specific fabrics without extra supports, the IPF ensures that all lifters compete on a level playing field, with the focus resting on their strength and technique rather than on the technological advantages of their gear.
