SFI 38.1 certified head and neck restraint
During our SFI 38.1 certification testing, the defNder™
recorded the following test results in both frontal and 30deg impacts.

Please note the consistency of performance of the defNder in both frontal
and 30deg impacts, with only 26lbs variation in neck tension. This shows
the effectiveness of the Motion-Max tether system which incorporates
VST (vertical stabilizing tether) geometry |
