Talking to a beemer rider the other day who had been given a new BMW helmet to try out which was effectively an open top ! It was open face only, but with two large panels in the top that were covered by a metal grille, rather than a conventional shell, a further panel low down at the rear was similar. The two top panels had close fitting clear plastic 'covers' for rainy days. About 60% of the conventional shell was missing. With the plastic removed you could see your hand through the top of the helmet
Has anyone seen or used one ?
