Getting The Fit Right: A Guide To Helmet Sizing
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 jacket built for riding, rather than a fashion jacket that merely looks the part, adds abrasion resistance across the shoulders and elbows, and many include pockets for armour inserts. Boots that cover the ankle protect a joint that takes real force in an off, and trousers or riding jeans extend that same protection down the leg.
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.
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.
Getting helmet sizing right starts with a proper head measurement, taken with a soft tape around the largest part of the head, just above the eyebrows and ears. That figure points to a starting size, but it is only a starting point, since head shape varies as much as head size.
