Performance in Motion

Tuned For Inland Fishing

Your Marbles are kitted with lenses designed to handle glare, shade, and variable light conditions on rivers and streams. Our light brown-tinted lenses remove unwanted glare from the waters surface and heighten contrast to help you spot fish and wade in turbulent water.

Tuned For Inland Fishing

Lens Tech You Can Trust

Polarization Efficiency

State of the art polarization cuts glare off water for less eye fatigue, better sight fishing and safer wading

Advanced Coatings

Hyrdrophobic coating allows for rain and spray to slide off instantly + anti-fog and anti-reflection allows for lazer focus on the water

Tri-Flection Mirror

The tint on The Trout Belly Flash keeps your lenses extra clean, repels smudges and reflects light.

Lightweight Polyamide

Impact resistant and so light you’ll forget they’re there
