Westin Flats Upf Shirt UPF 50+ S Mist Grey

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

The Westin Flats UPF (Ultraviolet Protection Factor) Shirt is built for anglers who spend long hours on the water in direct sun — combining UPF 50+ protection with a stretchy, fast-drying fabric that keeps you moving freely from first light to last cast.

Serious UV Defence Without Sacrificing Comfort

Rated UPF 50+, the Flats Shirt blocks the vast majority of harmful UV radiation — essential when you're exposed on open flats, a kayak deck, or a boat with no shade. The 85% polyester / 15% elastane blend dries quickly and moves with you, while raglan sleeves with flatlock seams eliminate pressure points and chafing during repetitive casting movements.

Smart Ventilation Details That Matter on Warm Days

Mesh panels positioned under the arms promote airflow exactly where heat builds up most, helping regulate body temperature even in warm, humid conditions. Thumb holes extend sleeve coverage over the back of the hands for extra forearm and wrist protection — useful when you'd rather keep casting than re-apply sunscreen.
