SMITH PIVLOCK ARENA MAX £120
The Max in the name alludes to the size of these glasses, their large single-piece lens offering excellent coverage. Numerous frame and lens options are available, ours coming with ‘sun-green mirror’ and an amber low-light version. The PivLock lens swapping system is the star. Hold the glasses, rotate the arm and out the lens pops. Quick, no force is required and you don’t even smudge the lens.
