А вот такие очки не хотите ли?

Наверное, их можно использовать и как шлем. Хотя, сомневаюсь.




spanish designer rodrigo canedo of canedo studio has sent in images of his latest work 'gladi8r shades'. the helmet-like frame's weight is distributed through the whole surface of the head, this not only ensures that the shades will remain in its place during use but also reduces friction in the usual supporting areas, such as nose-bridge and ears. the frame comes in 3 different sizes and it is adjustable through a range of rubber attachments that brace the ribs of the frame.
