Everything you need to know about your ski helmet construction.

While buying a helmet for skiing or snowboarding, you may wonder what you should know about its construction. Many styles and types may fit you if you remember about few important steps mentioned in a previous article. However, different types were not created without any reason. What should we know about them?
Most helmets are designed for a single large impact. If the impact is too big, the hard foam interior may collapse or cracks to soften and absorb the shock. In such a case the helmet should be replaced - it is no longer safe. Soft Shell (EPP) helmets are the exception, but may not be certified.
On the market, you will find:
In-molded construction has a thin, hard plastic outer shell. It is molded to an EPS foam liner to absorb shock. This setup allows for less rebound during the impact - it will simply collapse under hard impact. Such a helmet is also lightweight.
HARD SHELL ABS HELMETS
ABS construction utilizes a thick, tough ABS plastic shell. It is properly pre-formed and glued onto a pre-molded hard foam interior and liner. Thanks to this design, you are offered good protection and it is still budget-friendly.
SOFT SHELL HELMETS
These type of helmets are often designed for multiple, not single, but at the same time less intense impacts. However, there are exceptions. Many soft shell constructions now have 2 foam densities. With a softer foam against your head transitioning to a harder foam against the outer shell you can feel safe while hitting the slope.
You should also remember about proper venting, that every helmet has to offer. Almost all helmets feature some form of open, passive venting. It allows escaping excess heat and moisture. Generally, these systems are simple and can't be personally adjusted. Don't forget also that your goggles should fit comfortably with your goggle strap over the helmet.
There should be no gap between the helmet and the top of your goggles.
