The Propero III brings you incredible performance for an incredible price. It has more in common with the high-end S-Works Prevail while keeping you extremely safe and aerodynamic to boot. It comes ready for Specialized’s ANGi crash sensor and features a composite matrix internal reinforcement system developed by Specialized that allows for larger vents and greater cooling. 

Inside, you’ll find soft 4X DryLite webbing material that retains its shape and sheds moisture even during the sweatiest rides, and a MIPS insert that helps dissipate rotational forces that are oftentimes associated with concussions. The 4th Dimension Cooling System with Mega Mouthport provides optimal cooling and comfort on those hot summer rides. Specialized made sure to offer multiple colors and include reflective decals to help you stay visible and safe out there on the road. This is one of the most feature-packed helmets in this price range.
