A made to order helmet starts long before any material is cut. Measurements are taken, the intended use of the helmet is discussed, and a rider works with the maker to settle on a shell, lining and finish that suit them specifically, rather than picking from fixed stock sizes.

A leather trimmed helmet needs a little more attention than a plain shell, but the upkeep is straightforward. Dust and light dirt can be wiped away with a soft, dry cloth, Heroine Racer and any marks are best treated with a product made for leather rather than general household cleaners, which can dry the material out over time.

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.

Neither format is a universal answer. Weather, speed, journey length and personal comfort all play a part, and many riders end up owning one of each for different trips.

Full face and open face helmets suit different kinds of riding, and the right choice usually comes down to where and how you ride rather than looks alone. A full face helmet covers the chin and jaw, giving more protection in a wider range of impacts, and tends to suit faster roads and longer distances.

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.
