Fidlock is a patented technology uses a magnetic mechanical fastener for simple securing of the helmet strap. The buckle and snap are magnetically attracted, creating a high locking force that is much easier to use that a traditional “D-ring” strap. The Fidlock buckle passes both DOT and ECE standards with its metal to metal connection points when secured. We are able to replace a lost or damaged Fidlock buckle. Unfortunately, we are unable to retrofit a Fidlock into a helmet that does not have it from the factory.
