![]() Virginia Tech only recommends helmets that receive four or five stars. A helmet gets more stars if the testing indicates it does a better job of reducing injury. VT’s protocols evaluate a helmet’s ability to mitigate linear acceleration and rotational velocity, then assigns a ranking of zero to five stars. Of them, we like Virginia Tech’s STAR tests which were developed with a more modern understanding of head injuries than the CPSC’s test. There are voluntary and third-party tests outside of the CPSC test. Given all we’ve learned about brain injuries in the past 20+ years, the CPSC test is in desperate need of an update. However, the standard is old (adopted in 1998), and does not, for example, contain any language about mitigating rotational forces on the brain, nor does it lay down any standards for a full-face helmet’s chin bar. must meet a Consumer Product Safety Commission (CPSC) standard.

Sizes vary by brand, and most companies offer a fit guide to help you determine which size is best for your head. “ A helmet will protect you only if it fits correctly,” says John Thompson, Scott’s helmet product manager. The size and design of the vents is often more important than the quantity. The Giro Synthe, for example, has only 19 vents but is widely regarded as a well-ventilated helmet, while the Kask Valegro has a whopping 37 vents. You can’t judge a helmet’s cooling ability simply by how many vents it has. Don’t be fooled by the “more vents are better” mantra. Other helmets that prioritize impact protection, like downhill and some mountain bike helmets, often have fewer vents (more holes = less protection against rocks and sticks). Road and XC are the lightest and most-ventilated helmets out there, and in some cases not only vent well but actually enhance cooling over wearing no helmet at all by directing airflow through the helmet and over your head.
