About helmets:

• Helmets are used as protective headgear for two wheelers.
• The usual motorcycle helmet has an internal layer of polystyrene or polypropylene foam and an external layer made of plastic, glass, and other man-made fibres.
• The principal function of a helmet is to absorb the shock of a crash and thus put a stop to major injury to the brain, rather than preventing head and face crack.
• The external casing put off pointed substance from piercing the head and also saves from harming the inner liner upon contact with the road.

Product characteristics:

• The two types of helmets available are:
• Full face helmet
• Open face helmet
• The critical characteristics of the helmets are -- protection of head, clear vision through the visor, quick release chin strap and appropriate ventilation (in case of full face helmets).
• The outer shell is made from Acrylonitrile-Butadiene-Styrene (ABS) or Polypropylene or glass fibre plastic which is hard in nature.
• The inner side of the shell is expected to provide cushion to the rider and is made from regulated density concussion padding.
