ForceFlex® FF1 technology incorporates a patented, multi-injection molding of the lens with a flexible Thermo Plastic Urethane (TPU) frame. Due to this construction, it can achieve a military ballistic level impact resistance at over 1000 feet per second. The TPU material allows the frame to flex and fit individual faces from large to small. All ForceFlex® FF1 safety glasses meet military MIL-PRF-31013 clause 184.108.40.206 for high velocity impact protection and exceed ANSI Z87+. This achievement benefits consumers by providing unparalleled levels of protection. The dual material temples combine Thermo Plastic Rubber (TPR) for comfort and polycarbonate for durability. MCR Safety's Forceflex® FF1 eyewear is engineered to provide the highest level of innovation for consumers that demand the very best in safety.

High velocity impact safety glass test method is performed by shooting a 1/4" steel ball at a speed of 150 feet per second aimed at the center of the lens. The result is a Pass or Fail which determines that a lens must not chip, break, or crack and it must maintain its original position in the frame.
