SAWTOOTH EXPLR

One Frame. Every Condition. No Compromises.

Built for the alpine and beyond, the Sawtooth EXPLR is a modular performance eyewear system that includes three precision-engineered ZEISS lenses to match every mission. A polarized lens cuts harsh glare—ideal for fishing, driving, and long days near water. The high-contrast Velocity lens sharpens detail at speed, perfect for bike descents, ridge runs, and fast-moving terrain. And the clear lens keeps you covered during dawn patrol, night rides, or stormy ascents.
Designed for serious mountain athletes, the Sawtooth EXPLR adapts to light, weather, and environment with uncompromising clarity and fit—so you never miss a moment.

Engineered by ZEISS exclusively for Zirkel Optics, FUTR LenZ™ delivers maximum clarity, contrast, and durability—with RiPel™ lens coatings that resist water, oil, dust, and fog in motion.
