Most helmets on the market today are covered with Velcro loop to fasten devices like ID patches, IFF devices, and cameras. The attachment strength of Velcro loop material degrades over time, especially with repeated use and environmental wear and tear, so that even Velro attachment which may have been adequate when new can fail over time. Its strength is also dependent upon the compatibility of the Velcro hook on the mating device, which may result in an unreliable connection to the helmet.
The NFM HASP (Helmet Attachment System Pattern) replaces the Velcro loop with a structural web of high-strength composites that provide a stronger and more reliable system throughout the shell exterior. Devices can now be mechanically attached without fear of the connection failing. The HASP is also removable so that it is easily replaced even in the field if it does become damaged.
