Bays – Polarised Eyewear for Focused Sports Performance

The Bays are designed for anglers who need dependable performance in bright, changeable conditions. Built with a wraparound shape and considered frame geometry, they offer clarity, comfort and effective side-light reduction.

Designed for Sports Performance

The frame profile supports confident movement on the bank, providing stability and coverage without unnecessary bulk. The design helps maintain clear vision across active sessions.

Superior Side-Light Elimination

The wrap angle is engineered to reduce the ingress of side light, supporting a more focused view of the water. This helps improve visibility when scanning margins or observing subtle movements.

Lightweight & Robust Frames

A spring-loaded hinge system enhances comfort by adapting gently to the shape of your head. The lightweight construction supports long periods of wear without fatigue.

XBlok Surface Coating

XBlok technology applies a reflective coating to help reduce additional glare. This improves visual comfort and enhances your ability to read the water in bright conditions.

Why Choose Bays?

The Bays combine coverage, comfort and glare management in a clean, functional design. A reliable choice for anglers who need consistent polarised performance throughout the session.
