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, 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.

A handcrafted helmet shell starts with a base material, commonly fibreglass or a composite blend, layered and shaped by hand rather than produced purely by mould and machine. Each layer adds strength, and the shaping stage is where a lot of the time in production actually goes.

A helmet workshop in London works on a smaller scale than a mass production line, and that shapes almost everything about how a helmet gets made. Materials are chosen and checked by hand, shells are shaped and finished in small batches, and problems are caught by people who see every stage, not just a sensor on a line.

Once the shell is formed and cured, it moves through finishing: sanding, painting or leather trimming, and fitting the internal padding and retention system. Every stage is checked before the next begins, since a fault caught early is far cheaper to fix than one found at the end.

Trying a helmet on in person, and wearing it for a few minutes rather than a few seconds, catches problems a size chart alone cannot. Padding also settles slightly with use, so a helmet that feels snug when new is usually the right call.
