Evolution's HPH Cat 1 Helicopter Helmet has been certified as an approved helmet by the Department of Interior for use in Helicopters.




The EVO HPH is the first to complete the process of DOI approval which consisted of Attenuation test, Lenses certification and Impact testing by third party Lab, Dynamic Research Inc.  Evolution manufactures 5 different helmet lines to include the popular 252 which should be completed and certified in December 2019.  The process takes several months to completed because the list of testing requirements by the DOI was such that no one laboratory could complete all the steps required.

Following the EVO 252, the XPH and sub-models of the EVO 252 will be completed.
