Westin Flats Upf Shirt UPF 50+ 3XL Sage Green

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

The Westin Flats UPF (Ultraviolet Protection Factor) Shirt keeps you cool, comfortable, and shielded from harmful UV rays across a full day on the water — whether you're wading the flats or casting from a boat.

UPF 50+ Fabric That Works as Hard as You Do

Built from a stretchy 85% polyester / 15% spandex blend, the fabric dries fast, moves with you, and delivers UPF 50+ sun protection across every exposed inch. Raglan sleeves with flatlock seams eliminate pressure points and bunching, so nothing slows your casting stroke from dawn to dusk.

Ventilation and Coverage Where It Counts

Mesh panels under the arms push warm air out and keep fresh air flowing during high-intensity sessions. Thumb holes in the sleeves extend coverage to the back of your hands and forearms — exactly where the sun catches you off guard when your rod hand is up. A crew neck rounds out the coverage without feeling restrictive.
