Design notes
Above the treeline the problem stops being sunlight and starts being wind, spindrift and reflected glare off snow. Summit X adds tool-free TPU side shields that seal the gap between lens and cheek, while the Grilamid chassis keeps its shape at temperatures that make normal frames brittle.

Common questions
Summit X runs a Cat. 3 lens at 28 g (32 g shielded), which suits full-day coverage for ridgelines, scree and exposed traverse. 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.
