What is typically required for a wrestler to compete safely on the mat?

Wrestlers are typically required to wear a singlet and headgear for safety and uniformity during competition. The singlet is designed to provide a snug fit to prevent opponents from grabbing extra fabric, which can lead to potentially dangerous situations. Additionally, the headgear offers protection to the ears, which are particularly vulnerable to injury during matches. By enforcing this uniform requirement, the sport aims to minimize risks and create a level playing field.

The other choices do not prioritize the same level of safety or standardization. Wearing only shoes does not address the protection of the body or maintain the competitive standard of attire. Allowing any comfortable clothing could lead to inconsistent gear, which might interfere with the match dynamics and safety protocols. Competitive wrestling gear is expected, but it must include the specific items of a singlet and headgear to meet the established guidelines for fair competition and athlete protection.
