Costa Del Mar FERG Square Sunglasses - Performance Shielded Lenses

In this review of the Costa Del Mar Men's FERG Square Sunglasses the bottom line is simple: these are built for anglers and active outdoor users who need top-tier sun protection and functional details on the water. The FERG carries the legacy of Ray Ferguson with a sturdy square frame, integrated top and side shields, and a polarized lens that blocks 100% of UV, so the single biggest reason to buy is its purposeful design for bright, reflective conditions where glare and splash are constant concerns.

Key Features

• Top and side shields: Built-in shields reduce stray light and glare from above and the sides for clearer vision when on open water.
• Polarized 100% UV lens: Polarization cuts reflected glare and the full UV protection guards eyes during long days outdoors.
• Hydrolite rubber: Textured Hydrolite on the frame improves grip even when wet, keeping the glasses secure during movement.
• Vented adjustable nose pads: Adjustable, vented pads allow a custom fit and help airflow to limit fogging during high activity.
• Included cloth and case: Each pair ships with a cleaning cloth and protective case to clean, protect, and store sunglasses between trips.

Who It's For

The FERG is aimed at fishermen, boaters, and anyone who spends extended time around water where glare is the main visibility issue. The combination of shields, polarized lenses, and secure Hydrolite contacts makes them well suited to active users who need reliable performance rather than fashion-forward shapes.

Those who prioritize ultra-lightweight frames for all-day casual wear or want a very small or rimless profile should look elsewhere; the FERG leans toward performance with structure and shielding rather than minimalism.

Pros & Cons

Pros

• Excellent glare reduction thanks to polarized lenses and integrated side shields for clearer sightlines on water.
