Fortis "Isolators" Polarised Sunglasses - Square Black Frame / Switch Lens

Ergonomic Eyewear for Total Side-Light Elimination
A refined evolution of a Fortis classic, the Isolators have been redesigned to deliver maximum fish-spotting performance. Available in two frame styles—Round and Square—both models feature removable side shields engineered to block peripheral light ingress, enhancing clarity when scanning water for signs of life.

SWITCH™ lenses automatically adjust their tint to changing light — clearer in shade, darker in bright conditions.

• Great for: All-day sessions with changing light levels
• Effect: Automatically transitions between lighter and darker states based on UV exposure
• Why choose it: Maximum versatility for anglers moving between shaded and open water
