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 Epicurist 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.
None of this needs to be bought at once. Building a complete kit over time, prioritising the areas most exposed in a typical fall, is a realistic way to get there.
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.
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.
The trade off is scale. A workshop like this will never produce helmets as fast as a large factory, and that is treated as acceptable, since the aim is a considered, well finished helmet rather than the fastest one to market.
