Microshell helmets are made of a thin polymer sheet over a foam liner; Hardshell helmets have a hard polymer outer shell and a foam liner; when the liner is being bonded to the outer shell during the manufacturing process, it is Molded in the shell.

The internal circumference determines the size head that the helmet will fit.

Most helmets are tested and certified for a specific sport. Some helmets are approved for multi-sports, but only after passing the safety tests for both sports (i.e., snowsports and cycling). 

Cetification is established by a variety of governing bodies who set impact standards. Most helmets are certified or approved for a specific sport, except in the case of multi-sport helmets (i.e., a snowsports helmet might also be approved for cycling if it meets the cycling safety standards).
