A helmet has a generally dome shaped helmet body with inner and outer sides and a lower edge extending generally in the shape of a loop; an elongated reinforcement member is embedded in the helmet to extend proximate the looping lower edge portion; that member may have band shape; and additional such band shaped reinforcement members may extend within the dome shape of the helmet. Openings may be provided through the body to pass retention straps, a first strap holder configured to be supported at and by the outer side of the helmet, the holder attached to at least one strap that extends through one of the openings, and the holder operable to transmit strap tension to the helmet. The holder typically holds two strap ends, and defines slots through which the straps pass for adjustable retention by the holder. |
