British Mk4 Aircrew Flying Helmet
The Mk4 Series is described in the Mk4 sereis overview, this page details specifics of the Mk4.
The liner of the Mk4 was similar to early Mk2 and Mk3 helmets, in that it was a single piece liner, continuing all around the helmet opening, attached to the helmet shell in a similar manner to the Mk2 and Mk3 helmets. All subsequent models of the Mk4 series used a simplified two-piece liner in the form of a brow pad and nape pad.

Quote:
The Mk4 aircrew protective helmet is currently under development. Some early models are in use with particular aircraft types. The basic helmet follows similar design principles to the Mk3 helmet with the following exceptions:
a. Slightly reduced weight.
b. Enlarged facial aperture to minimise vision reduction.
c. Larger neck 'cut-away' at nape of the neck to increase neck mobility.
d. Completely redesigned communication system and ear capsules to give markedly improved noise attenuation and communication properties.
