Giro
Although it is a subsidiary of Bell, Giro designs have been known for a unique fit and a trend leader. The line has been gradually evolving and adding rounded compact profile models over the past several years, but the most expensive high-end models still have the elongated shape and pronounced external points. All Giro helmets are molded in the shell, and high end models have lower shells molded in as well. High-end models use fitting pads, but the less expensive ones are ring fit. This year Giro has highly visible neon colors again. Some Giro helmets have reflective surfaces on the rear stabilizers, a logical place for those who ride in the bent-over position. Visors are mounted with pins that snap into the helmet shell and have an adjustable angle. Our unscientific hand test showed them to pop out readily on impact. Strap fittings are not among the best for holding securely after adjusting, although those on the Aeon and Rift models do hold well.
Bell, Giro and other manufacturers have lighter hyper-ventilated models produced for the European market that meet the CEN standard but are not certified to meet the tougher US CPSC standard.
