EP stands for Ear Protection, also known as Ear Pro. It’s an essential piece of kit but can make your glasses fit uncomfortably, so we fixed that. Tested with elite operators for over two years, the SR-1EP is engineered to be downrange, in training, or on jobs where ear and eye protection is crucial. The temple arms feature GEKO™ Lite, a molded-in version that is thinner to fit comfortably under Peltors and similar ear pro. The ANSI Z87+ certification ensures high velocity and high-mass impact protection, meaning the SR-1EP is professional grade and duty ready.
