A helmet that is the right size should feel snug all the way round with no single pressure point, and it should not shift when you turn your head firmly from side to side. A helmet that moves independently of your head on a shake test is not the right fit, regardless of what the size label says.
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.
Sun and heat are the two things to watch for. Leaving a helmet on a dashboard or in direct sun for long periods will dull and eventually crack leather trim, so a helmet bag or a shaded spot makes a real difference over the life of the helmet.

This is slower than fully automated manufacturing, and that is the point. A handcrafted shell trades speed for a level of finish and individual attention that a purely machine made helmet does not offer.
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.
