Introducing the ultimate American-made flannel shirt: the Devium Boca Long Sleeve Flannel.

Crafted from mid-weight yarn-dyed 100% cotton flannel, this shirt is a true testament to our commitment to great quality and sustainability. Each piece is made in the USA and carefully crafted by legacy small businesses in California, Missouri, Pennsylvania, and North Carolina – showcasing the best of American craftsmanship.

But it's not just about where it's made – it's also about how it's made. Our superior double-needle stitching ensures durability and longevity (and a great look) for years to come. And with burly engraved 26L cat-eye buttons, our flannel shirts aren’t “menswear” – they’re a statement reflecting a classic yet more rugged styling.

Not only is this flannel tough, but it's also incredibly soft, making it the best flannel shirt for men who prioritize comfort. The fabric is pre-washed and double-brushed for a luxurious feel against your skin – perfect for those chilly fall evenings or outdoor adventures.
