This padded suspension system provides greatly increased wearing comfort for your helmet. It's the same suspension system as used in the British combat helmets, but designed to retrofit easily into the U.S. PASGT helmet. It installs easily, with only a screwdriver required. It features a three-point strap system so that the helmet stays firmly on your head, without tipping forward, through a full range of movements. One size adjusts to fit all helmet sizes. Required hardware and instructions included. Made in England. Once you've used this suspension system in your PASGT helmet, you'll feel sorry for those who don't have one!
