The Cal Praesidio
Virginia Tech’s Newest 5 Star Rated Helmet. By utilizing a single layer or multiple layers of variable durometer foams, we are able to dramatically reduce impact forces and reduce the severity and incidence of concussion.
5 Star Rated Helmets perform the very best at reducing impact forces and protecting athletes from TBI and concussion.
“A helmet's rating is comprised of two components: the STAR score and the number of stars.
STAR stands for the Summation of Tests for the Analysis of Risk, and the STAR score is calculated based on a helmet's performance in a series of impact tests. The impact conditions are sports-specific and inclusive of the broad range of head impacts that athletes are likely to experience. STAR is based on 2 fundamental concepts: 1) tests are weighted based on how often people experience similar impacts and 2) helmets that lower linear and rotational head acceleration reduce injury risk.
A helmet with a lower score offers better protection. STAR scores are assigned a number of stars to categorize impact performance. The number of stars varies between 1-5, with 5 stars being the best.
These methods have been published as peer-reviewed articles in journals such as Annals of Biomedical Engineering.”
