ECE 22.06 is the current European standard that motorcycle helmets are tested against, and it replaced the older ECE 22.05 standard with a wider and more demanding set of tests. Helmets are checked for impact absorption at multiple points on the shell, not just the crown, and the standard also tests rotational forces, which earlier standards largely ignored.
An open face helmet leaves the face exposed, which some riders prefer for shorter journeys, city riding, Hedon or a more classic look on a café racer or scrambler. It offers less coverage than a full face design, and riders who choose one should weigh that trade off honestly rather than assume it based on style.
A certified helmet carries a label inside the shell showing the standard it meets, along with a homologation number that identifies the specific model tested. This label is worth checking on any helmet, since it confirms the exact helmet in your hands passed the test, not just the range it belongs to.
The trade off is scale. A workshop like this will never produce helmets as fast as a large factory, and that is treated as acceptable, since the aim is a considered, well finished helmet rather than the fastest one to market.
Certification is not a formality. It is the baseline that separates a genuine protective helmet from something that only looks the part. Any helmet worth wearing on the road should carry a current, verifiable certification.
The liner deserves the same care. A removable, washable liner keeps the inside fresh, and following the maker's washing instructions protects both the padding and the stitching around it.
