Pro-Tec skate helmet was developed in 1970s. It was widely adopted by the US military as a bump helmet. Many US SOF operators modified it for HALO parachute jumps. The modified Pro-Tec helmet featured here has bayonet lugs attached to the sides for an MBU-12/P oxygen mask. There is a boom mic mount base located at the bottom left for communication setup. The front of the helmet has a block made by duct tape to secure the skydiving goggles from sliding off when it is over the helmet. This setup was very popular in the 1990s.
