Thor - Guardian Protector The Thor Guardian Protector is the more comprehensive version of the Guardian MX, adding adjustable suspension shoulder guards and adjustable removable bicep arm guards (both with molded comfort liners) on top of the chest, back, and Stone Shield protection. Same EN-certified Stone Shield front (EN 14021:2003) and back protector (EN 1621-2:2014). Why We Like It: The bicep arm guards are the meaningful difference vs. the Guardian MX. They protect more of the upper body without going to a full body armor jacket, and the suspension shoulder guards distribute the load instead of bunching at the collar. Why It’ll Work for You: Best for riders who want broader upper-body coverage than the Guardian MX delivers, especially for trail or rocky terrain where bicep contact happens. Adjustable straps mean it scales to different rider sizes. Key Features: Press-Fit molded comfort liner system for a smooth inner chassis Adjustable waist buckle closure system Level 1 back protector for impact energy reduction Stone Shield panels protect from lofted stones and debris Strategically placed ventilation ports Refined fit for maximum deflector coverage Adjustable suspension shoulder guards with molded comfort liner Adjustable and removable bicep arm guards with molded comfort liner Stone Shield tested and certified to European Standard EN 14021:2003 Back protector tested and certified to European Standard EN 1621-2:2014 Complete The Kit Round out your ride gear with Thor jerseys, Thor pants, the latest Sales on Thor gloves, or the latest Sales on Thor gear.
