I've worked on making alot of helmets over the years (bike, bike dh, skate, snow & moto). The protec helmet tested doesn't do much (the test lab provides proof), it does protect against lacerations minor penetrations, but in regards to protecting the gray matter which does matter it's NOT very protective. What is protective is CPSC qualified bike helmets, these types of helmets are designed to protect against life threatening injury mechanisms (major brain tram such as skull fractures), inherently these types of helmets also do a great job of protecting against a wide range of injuries that occur from minor falls at slow speeds to very dynamic high speed crashes. For those who think they can control there fall, there playing odds and you will loss at some point.. I've seen a lot of helmet carnage, and so often the circumstances are one that the rider had no control over how they fell... If it's a bike helmet in USA it is the federal law to comply with the CPSC specifications. There should be a sticker saying so in each helmet. Wear a CPSC qualified helmet properly and expect to have excellent protection. Wear a DH ASTM-1952 helmet and expect additional protection on the sides and rear, plus the chin. You can find a list of helmets that have been reviewed by a non profit group called the Bicycle Helmet Safety Institute. The BHSI annual bicycle helmet report is at the link below. http://bhsi.org/helmet12.htm So safe travels and have fun ripping it up! It's been a great winter of riding so far...
