Gel Defender Test Results
GELDEFENDERTM TESTING FOR G-FORCE REDUCTION AND COOLING BENEFITS
Reducing g forces from impacts and keeping players cooler are the two primary reasons we developed GelDefender® Helmet Liners.
That’s why we put GelDefender® Helmet Liners through rigorous impact and thermal tests. Researchers at ICS Laboratories in
Brunswick, OH tested GelDefender® Helmet Liners in football, baseball, softball, ice hockey and skateboard/bicycle helmets; in military
ACH helmets and industrial hard hats; and independent of helmets.
*Test helmets were new, unused helmets made by major manufacturers.
Testers at ICS Laboratories began by collecting baseline measurements using helmets worn in various activities. These helmets
were placed—without GelDefender® pads—on headforms attached to devices that record impact data.
The headforms, a substitute for human heads in tests, were placed inside the helmets and dropped from various heights to strike
at various locations on the helmets. Then, the tests were repeated after adding GelDefender® Helmet Liners to the headforms, and
the results “with” the GelDefender® products were compared to the results “without” the Gel Defender products.
GelDefender® Helmet Liners reduced g-forces impacting the headforms by 12%-74%, depending on helmet type and impact location.
Scientists have no conclusive evidence as to whether or how the reduction of g forces during impacts reduces the number or degree
of concussions and head injuries. Participants in activities in which head impacts can occur should always use tested and approved
helmets for protection. However, no helmet or extra padding can protect the user from all serious head or neck injuries that can result
ABOUT ICS LABORATORIES
