A certified helmet carries a label inside the shell showing the standard it meets, along with a homologation number that identifies the specific model tested. This label is worth checking on any helmet, since it confirms the exact helmet in your hands passed the test, not just the range it belongs to.
A clean visor is a safety item as much as a comfort one, since scratches and haze scatter light and make it harder to judge distance in low sun or at night. Clean a visor with lukewarm water and a soft cloth,

Full face and open face helmets suit different kinds of riding, and the right choice usually comes down to where and how you ride rather than looks alone. A full face helmet covers the chin and jaw, giving more protection in a wider range of impacts, and tends to suit faster roads and longer distances.
Anti fog inserts and coatings help in cold or wet conditions, but they are not a substitute for a visor in good condition. Once scratches build up to the point where they catch the light on every ride, it is time to replace rather than keep cleaning around the problem.
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.
An open face helmet leaves the face exposed, which some riders prefer for shorter journeys, city riding, or a more classic look on a café racer or scrambler. It offers less coverage than a full face design, and riders who choose one should weigh that trade off honestly rather than assume it based on style.
