The Fortis Isolator Square Polarised Sunglasses are a refined evolution of the classic Fortis Isolator, re-introduced as a much-requested upgrade. Designed as out-and-out fish spotting tools, they aim to eliminate as much unwanted light ingress as possible, with removable light blockers that allow for easy transitioning to everyday wear. Available in two distinct styles – Isolators Round and Isolators Square – these sunglasses are built for maximum performance on the water. The removable side shields are engineered to block peripheral light ingress, reducing glare and enhancing visual clarity when it matters most. Whether you are searching for that next fish or heading off the water, the detachable shields offer seamless versatility. The matte black frame is complemented by metal Fortis logos on each temple, while soft rubber arm tips ensure all-day comfort.
