Concussions have a natural born enemy in the Cascade M11 Limited Edition Helmet. A revolutionary liner system, dubbed Seven Technology, provides the protection of two helmets in one by dispersing impacts laterally and resetting immediately for additional impacts. Combined, this gives you one of the most advanced and protective helmets available today. And if that weren't enough, it's great looking too. * Limited Edition black with chrome accents and ventilation vents * Once they're gone...they're gone...only 1,111 will be produced * Seven Technology liner system utilizes a ground-breaking impact attenuation system tuned to absorb impact using lateral displacement * Seven Technology behaves like two helmets in one one for catastrophic hits and one for concussions * Within milliseconds, the liner completely resets to ready for the next impact * Total reset capability is proven to perform better than EPP (the foam liner in standard hockey helmets) on successive impacts * Mono 90 shell offers a lightweight stream-lined design * 90/10 shell configuration is lighter, faster, stronger, and reduces direct energy transfer * Dynamic system provides a lower neck adjustment that eliminates pressure points * Ratchet system for tool-free size adjustments * 20 Air vents for maximum air flow * HECC and CSA certified cage
