Westin Flats Upf Shirt UPF 50+ S 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 through every session on the water — from first light to last cast.

Built to Move with You

Raglan sleeves cut from a stretchy 85% polyester / 15% spandex blend eliminate shoulder seams and allow a full, unrestricted range of motion. Flatlock stitching lies flat against the skin to prevent chafing during long days in the boat or on the flats.

Engineered for Heat and Glare

Mesh panels under the arms actively ventilate the shirt, letting heat escape so you stay focused rather than overheated. Thumb holes extend coverage to the forearms — a practical detail that matters most when the sun is low and reflecting off the water. The fast-drying fabric means you won't stay damp after a splash or a sudden rain shower.
