Visors are a wear item, not a lifetime part of the helmet, and most riders find a spare on hand is worth having, especially before a long trip.
Neither format is a universal answer. Weather, speed, journey length and personal comfort all play a part, and many riders end up owning one of each for different trips.
A helmet is the most visible piece of riding gear, but it works as part of a wider kit rather than on its own. Gloves protect hands in a low speed drop, which is one of the most common types of fall, and a good pair balances grip and feel with real abrasion resistance.
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.

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.
