Flannel Shirts

Soft, warm and naturally comfortable, flannel is a fabric defined by feel as much as function. Our collection of men’s flannel shirts is designed for everyday wear, balancing relaxed construction with thoughtful tailoring and understated detail.

Made from brushed cotton and flannelette fabrics, each flannel shirt for men offers warmth without weight, making it ideal for layering through cooler months. From classic checks to clean, solid finishes, these styles are easy to wear and versatile in character, equally suited to work, weekends, and everything in between. Whether worn on its own or layered over a T-shirt, a well-made flannel shirt brings texture and ease to modern wardrobes, delivering comfort that improves with wear.

About Our Flannel Shirts

Flannel has long been valued for its softness and insulating qualities, making it a staple fabric for transitional and winter dressing. Our men’s flannel shirts are crafted in England and Europe using premium cotton fabrics selected for durability, comfort, and responsible sourcing.

The collection includes both brushed flannel and flannelette shirts, offering varying weights and finishes depending on the season. Clean lines, considered fits and subtle detailing ensure each flannel shirt feels refined rather than rustic, bridging the gap between casual and smart. For a more elevated option, selected styles work well as men’s dress flannel shirts, offering warmth while maintaining a clean silhouette.

Designed to be worn year after year, these flannel shirts for men can be styled open as relaxed overshirts or worn buttoned through as part of a modern casual shirts rotation. Paired with knitwear, trousers or denim, they offer understated versatility and comfort. Built with longevity in mind, they reflect Oliver Spencer’s commitment to craftsmanship, provenance and modern utility, timeless pieces made for everyday wear.
