The integrated snorkel mask may be a half-mask, which encloses the eyes and nose but excludes the mouth, or a full-face snorkel mask, which covers the eyes, nose, and mouth. Early designs of snorkel-mask typically comprised a tube for breathing with an immersion-activated shut-off valve at the top, and the bottom opening into the mask, which ...

The FAST XR Helmet System released in 2022 represents an intermediate in protection between the SF line of helmets and the RF1 Helmet System, protecting against 7.62×39mm rifle rounds at a distance of 10 feet, but not against larger rounds such as 7.62×51mm. This is due to having a shell thickness of 0.280" (7.112mm).
