Romeo Doubs wears a padded helmet cover called a Guardian Cap, which is a soft-shell cover that fits over the traditional helmet. This cap is designed to reduce the risk of concussions and head injuries by absorbing and redirecting the force of impacts during play. Doubs started wearing the Guardian Cap after recovering from a concussion, and the NFL allowed the use of these caps in games starting in 2024. The cap acts as an additional buffer to slow down the force on the skull during collisions, thereby lowering the chance of concussion injuries.
