Unlike the amazingly popular Radar glasses, which use a more conventional single-piece lens design, the new Jawbones use independent lenses and have an aggressive look that’s evolved from the late Racing Jacket design.
The key feature of the Jawbone is the incredibly easy Switchlock lens changing system – the nosepiece swings to allow the lower part of the frame to open and the lenses to slide out.
There’s the option of both black iridium and high intensity yellow lenses –our Jawbones were finished in the Retina Burn yellow, which adds to the bug-like look.
The optical clarity is phenomenally good – there is no distortion of trail obstacles and you won’t be getting any headaches from these lenses either.
There are two pairs of nosepieces to suit different nose shapes, and they’re coated with the same Unobtainium rubber as the ear pieces – which stick to your ears even more when wet.
We found the Jawbones comfier than both the old Racing Jackets and the de rigueur Radar, and their vented lenses – which come as standard – resist fogging better than virtually all other eyewear.
The only downside is that coverage isn’t quite as good for those with dodgy noses, whereas the different lens size options on the Radar can compensate for odd-sized facial features.
