The Shred Ready Outfitter Pro features an updated retention system that is not only durable, but also replaceable. Specifically designed to handle the day to day abuse of the commercial outfitting industry. Traditionally only sold to Professional Outfitters, Liveries and Swift-water Rescue Agencies, this improved design is now available to everyone. The size Large is very accommodating for big heads, fitting up-to a 63cm (24.8") 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 (20") circumference. A durable, dial-style retention band provides a wide sizing range and keeps the helmet secure and comfortable. No removable pieces mean no drama because there's nothing to lose. Available in the primary colors for traditionalists and Flash Green for those who want some flash. This can be an affordable option for personal protection, and an ideal option if you need to outfit a rotating tribe of weekend warriors!
