Built for hikers and backpackers who count every gram, these sunglasses feature an aerospace-grade Aluminium-Magnesium (Al-Mg) alloy frame — one of the lightest metals used in outdoor gear. You'll barely notice them on your face, even on full-day summit pushes.
⚖️ Ultralight Construction
Al-Mg alloy frames are significantly lighter than standard plastic or steel frames, keeping your pack weight and your face weight to a minimum.

Prescription-compatible — available in myopia lenses from -0.75 to -6.00, so you don't have to choose between vision and protection
