Here is what you need to look for when buying an MTB Helmet

You can buy two styles of MTB helmets, one with an open face design and another with closed face design. With the open face model, it looks like a standard helmet with a lightweight design. The helmet has an aerodynamic construction and is well-ventilated. Furthermore, it has an EPS liner that is either molded or glued to the shell.

Other features to look at:
