The shells themselves are preferably of A.B.S. though where greater strength is required the outer shell 4 may be made from fibreglass-reinforced synthetic resin. The inner shell 6 may be provided with raised ribs 10 to provide ventilating passages, and also, if desired, with a soft resilient padding slot 12 may be formed in the inner shell 6 for the anchorage of lugs 13 for securing a head band, (not shown) within the helmet. Similar lugs may also be provided for an occipital strap or chin strap or both.
