This straps were easily installed and hold my Ess profile goggles nice and tight. I recommend these to any one with a helmet and goggles.
neat little item, works with PASGT helmet, too
The straps keep eyewear in place, as advertised. You can also make them work with the PASGT helmet by attaching them to the small screw and t-nut by the ear, rather than the mounting screws in the rear.
It's not as convenient as having the straps in the rear, but it works, and your eyewear won't launch itself off your helmet.
