The Shred Ready Outfitter Pro Helmet is the result of years of rigorous testing from our wholesale customers. Traditionally only sold to Professional Outfitters, Liveries and Swiftwater Rescue Agencies, this improved design is now available to everyone. Four sizes offer a personal fit. The size Large is very accommodating for big heads, fitting up-to a 63cm (24.8in) head circumference. The size Extra Small is a great choice for youth and adults with smaller heads, giving a snug fit down-to a 50.8cm (20in) circumference. A durable, dial-style retention band provides a wide sizing range and keeps the Shred Ready Outfitter Pro Helmet secure and comfortable.
