Nightbird Three Gold navigator sunglasses: Oakley’s iconic Sub Zero navigator sunglasses are back for a limited time - 30 years after their first release. Original features - such as the unique, futuristic-inspired lense shape - remain in dark grey, alongside new features that promise comfortable wear and enhanced vision on hikes, bike rides and days spent sightseeing. Think super-strong - but super-lightweight - O Matter® frames in black and CH0105S 001 navigator sunglasses to enhance colour and contrast while you take in the views. You’ll also discover Unobtainium® nose stripe-detail and earsocks, which guarantee a comfy, no-budge fit.
