The Weatherproof Vintage Men's Long Sleeve Flannel Plaid Shirt is a classic button-down flannel crafted for comfort and casual style. Made from a soft, double-brushed 60% cotton and 40% polyester blend at approximately 160 GSM, the fabric delivers warmth without bulk and is pre-shrunk to minimize shrinkage after washing.

The shirt features a yarn-dyed plaid pattern in a gray colorway and is offered in a tall extended size (XXL Tall). Design details include a button-down collar with chambray trim at the interior neckband and back yoke, a single chest pocket with button closure, back pleats for ease of movement, and a curved shirttail hem. Available in multiple plaid colorways across the broader Costco assortment, making it an easy choice for layering during cooler months.

Machine wash cold with like colors on a gentle cycle; tumble dry low.
