Peacekeeper International (also known as Dummies Unlimited) is known for its dummies used for DT training, but the company now also sells Peacekeeper DT Suits. The Pro Flex Instructor Suit is made to provide maximum protection and the Dyno Flex Student Suit is made for maximum mobility. Both have a one-piece lightweight design so you can take them on and off in less than a minute. Peacekeeper DT Suits include head protection with removable face guards and are available in small/medium and large/extra-large sizes.
