Westin Flats Upf Shirt UPF 50+ L Mist Grey

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

Built for long sessions on exposed flats and open water, this long-sleeve performance shirt keeps you cool, comfortable, and shielded from the sun without sacrificing freedom of movement.

UPF 50+ Protection from Dawn to Dusk

The fabric carries a UPF (Ultraviolet Protection Factor) 50+ rating, blocking the vast majority of harmful UV radiation — essential when you're spending hours on the water with no shade. Thumb holes at the cuffs extend coverage to the forearms, closing the gap that standard sleeves leave exposed.

Stretch Comfort and Active Ventilation

The 85% polyester / 15% elastane blend is stretchy and fast-drying, moving with you rather than against you during casts, net work, or long paddles. Raglan sleeves with flatlock seams eliminate pressure points at the shoulders, while mesh panels under the arms channel airflow to keep core temperature down on warm days.
