Fantastic protection for alpine environments and extreme light conditions. The flash lens treatment provides even light filtering and an anti-reflective coating removes stray reflections and glare.
- Spectron 4 polycarbonate lenses have a 6-base curve that minimizes distortion
- Flexible frame provides comfort and good hold
- Side vents at temples
- Cord retainer attachments
- Category 4 lenses transmit only 5% of visible light. Great for glaciers, but too dark for driving or everyday wear
