Drift
Hand-polished acetate and a mineral-tone G15 lens — the pair you wear to the trailhead and forget to take off.
- Bio-acetate frame, hand-tumbled for a deep gloss
- G15 lens preserves natural colour reading
- Five-barrel hinge with stainless rivets
Design notes
Not every ride is a summit day. Drift uses a bio-based acetate sheet cut and tumbled over three days, so the colour runs through the material rather than sitting on top of it. The G15 lens is deliberately unfashionable: it does not change how reds and greens read, which matters when you are reading terrain.

Common questions
Drift runs a Cat. 3 lens at 26 g, which suits acetate and crystal frames that survive the city and the trailhead. If your route crosses snow or glacier you need Category 4 filtration instead — take the Glacier Shield. If you are unsure, email us your route and we will tell you straight.
Rinse under running water before wiping — trail dust is abrasive and most coating damage happens when grit is wiped dry into the surface. Use the supplied microfibre pouch, never a shirt. Avoid solvents and sunscreen on the lens; DEET and alcohol will attack the coating permanently.
Two years from delivery, covering hinge failure, frame cracking under normal use, coating delamination and failure of the rubber grip components. It does not cover cleaning scratches, lost pairs or impact damage — though replacement lenses are cheap and available.
