Westin Flats Upf Shirt UPF 50+ M Mist Grey

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 flats, whether you're wading shallow saltwater or casting from a boat.

UPF 50+ Protection Without Compromise

Built from a stretchy 85% polyester / 15% elastane blend, this long-sleeve shirt blocks over 97% of UV radiation while the fast-drying fabric keeps you from overheating. Raglan sleeves with flatlock seams eliminate chafing and allow a full range of casting motion, so nothing slows you down between strikes.

Ventilation and Fit Designed for Warm-Water Fishing

Mesh panels under the arms promote airflow exactly where you need it most during warm, humid days on the water. Thumb holes at the cuffs extend coverage to the forearms without needing a separate buff or glove. The crew neck and normal fit sit comfortably under a life jacket or wading pack, and the two-tone Mist Grey colourway with Westin branding on the chest and right sleeve keeps things looking sharp.

Choose the Right Variant

The Flats UPF Shirt is available in two colourways — Mist Grey and Sage Green — each offered across a full size range. Both colours deliver identical UPF 50+ protection and the same technical construction. Choose the size that matches your chest measurement using the Westin size guide.
