According to MA2, what must participants in mounted services wear?

Participants in mounted services are required to wear an ASTM-SEI or international-equivalent equestrian-specific helmet for safety reasons. This standard emphasizes the importance of head protection while engaging in activities that involve horseback riding, as falls and accidents can result in serious head injuries. The ASTM-SEI certification indicates that the helmet meets specific safety standards designed to protect riders.

While other items like a cowboy hat, riding crop, and reflective vest are associated with horseback riding and can enhance visibility or provide guidance during riding, they do not serve the critical protective function that a helmet does. The mandatory requirement for wearing a helmet aligns with best practices in safety protocols for mounted activities, making it a non-negotiable aspect of participant attire in these contexts.
