Westin Flats Upf Shirt UPF 50+ XXL Mist Grey

Westin Flats UPF Shirt — Full-Day Sun Protection for Saltwater Anglers

The Westin Flats UPF (Ultraviolet Protection Factor) Shirt keeps you comfortable and shielded from harmful UV rays during long sessions on the flats, whether you're chasing bonefish at sunrise or working the shallows until dusk.

UPF 50+ Protection Without Sacrificing Comfort

The 85% polyester / 15% elastane fabric blocks over 98% of UV radiation while stretching with every cast. Raglan sleeves with flatlock seams eliminate pressure points and friction, so you can fish all day without restriction. Thumb holes extend coverage to the forearms — an often-overlooked area on exposed saltwater flats.

Built-In Ventilation for Warm-Weather Fishing

Mesh panels under the arms promote airflow exactly where you need it most, helping to regulate body temperature when the sun is high and the air is still. The fast-drying construction means the shirt handles spray, sweat, and unexpected rain without staying wet, making it a reliable choice for tropical and warm-season saltwater outings.
