To ensure optimal comfort and safety, each ATRA 20 helmet is equipped with a 4-point chin strap and and a 6-point shell-mounted tether. In addition, customers can choose from two types of tether (fixed tether and swivel tether) for a better, customized fit to their head shape.

*The influence of external factors from the environment in which the helmet is used has a very strong effect on its durability. Inadequate storage, lack of regular cleaning of the helmet, or excessive exposure to chemicals or UV radiation can significantly shorten its shelf life. Shelf life should not be construed as a manufacturer's warranty.
