No Slip. No Bounce.
Engineered for active movement without constant readjustment.
Adjustable Nosepads
Adjust to your exact nose fit, allowing proper lift and stability for different nose profiles.
Flexible Temples
Custom-tune the arms to your exact head width. A personalized fit for every individual, not a one-size compromise.
Lightweight Construction
Balanced weight distribution keeps the frame stable without creating pressure points. So light, you’ll forget you’re wearing them.
No-Slip Grips
Textured grip zones help reduce slipping during movement. Adds stability without excessive pressure, keeping the frame secure as you train.
High-Performance Lenses

ImpactPro™

Enhanced Airflow

True Depth Perception
Our non-polarized lenses don’t filter natural light, helping you judge distances effortlessly. (that’s why many pro athletes prefer non-polarized lenses.)

Experience uninterrupted vision with lenses that wrap around your face, keeping you protected from the elements. Full coverage. No blind spots.
UV400 Protection
Blocks 100% of harmful UVA & UVB rays, shielding your eyes during long outdoor sessions. Train longer. Stay protected.
