The Bolt were created for competition use.
The special shatterproof lenses have an external scratch-proof and anti-UV treatment and the inner has an anti-fog treatment; they have no waterproof seals, because their special shape is designed to fit right into the eye socket.
The minimum overhang of the lenses guarantees excellent visibility and minimum friction with the water so as to favour high-speed performance.
They come with the main parts disassembled
: lenses, latex strap, plastic nose-piece and small line to assemble the nose-piece.
