Vintage Osh Kosh workwear denim jeans featuring a warm red plaid flannel lining, perfect for cold weather or outdoor labor. These rugged straight-leg pants showcase a classic medium wash with authentic distressing, including fraying at the pocket edges, a worn buttonhole, and heavy wear at the leg openings that reveals the inner lining. Built for durability with reinforced belt loops and a heavy-duty zipper fly, these jeans provide both a heritage aesthetic and functional warmth.
