Westin Flats Upf Shirt UPF 50+ XL Sage Green

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

The Westin Flats UPF (Ultraviolet Protection Factor) Shirt keeps you cool, covered, and moving freely whether you're wade-fishing the flats or working the deck from first light to last cast.

UPF 50+ Protection Without the Bulk

The 85% polyester / 15% spandex blend blocks harmful UV rays to a UPF 50+ rating while remaining lightweight and fast-drying. Mesh ventilation panels under the arms promote airflow so you stay comfortable even in intense heat, and the stretchy flatlock seams prevent chafing during long sessions.

Built for Unrestricted Movement

Raglan sleeves cut from shoulder to cuff eliminate restrictive shoulder seams, giving you a full range of motion for casting, paddling, or handling fish. Integrated thumb holes extend coverage over the back of your hands — a practical detail that makes a real difference when the sun is low and forearm exposure creeps up.
