This helmet is brand new old stock and comes with original issue paperwork,see picture above.

The Mk 6 alpha helmet was the standard combat helmet of the British Armed Forces. The jump in MK numbers is thought due to the confusion surrounding the MK IV helmet utilising the MK V lining, introduced in 1959. . The MK 6 alpha, introduced into service from 1985, is designed to accept modern ear protection, personal radios, and respirators. The helmet is manufactured by NP Aerospace, and is reported to have an "almost unlimited service life" by the manufacturer.

The helmet in its default configuration is a alpha. The army use covers to camouflage the helmet and adapt it to different environments. Covers include the British Disruptive Pattern Material in temperate, woodland and desert patterns, a pure white cover for arctic environments and a United Nations blue coloured cover. It is sometimes referred as the "battle bowler", a term first used for the Brodie helmet.

The Mk 6 alpha is often mistakenly thought to be made out of kevlar when in fact it is constructed of "Ballistic Nylon" - nylon fibre.

From June 2009 the helmet was replaced by the Mk 7 helmet.
