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 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 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.

To see the current range built this way, visit Hedon Helmets.

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.
