In 1985, the original Giro Prolight set the standard for modern light-weight cycling helmets. Now, 25 years later the new Prolight redefines what an ultra lightweight helmet can be. After an exhaustive, groundup design and engineering process, we’re confident that our new Prolight is the lightest game in town. Bar none. And it’s remarkably well ventilated and comfortable too - a labyrinth of optimized internal channels allows the helmet to exhale hot, stale air like no other. And by specifying Italian made, featherweight webbing along with our new, minimal Roc Loc SL fit system, you’ll have to remind yourself that you’ve got a helmet on at all. Designing the Prolight was a true exercise in restraint that reminded us that simplicity really is the most important element of style. And performance.
