British Mk5 Aircrew Flying Helmet

Known as the HSAB, High Speed Air Blast helmet, it was designed for high speed ejections, intended for use in the Tornado, but I believe never entered full service.

Made by ML Aviation Ltd, resembling a motorcycle crash helmet, it was a one-piece helmet providing impact protection, wind blast protection, communications, and oxygen via an in-built mask.
