Classic Flannel Shirt design inspired by Special Forces heritage. Constructed from midweight drill cotton with a brushed twill weave, chosen specifically for additional breathability and durability. Designed with a loose fit to be worn as an overshirt.

Of proud British origins, Flannel fabric was first conceived in the 17th century as the preserve of Welsh farmers. These early pioneers discovered that when brushed on both sides fabric becomes sturdier, providing a thicker, more durable and insulating layer without losing its comfortable feel. Flannel would soon become the go-to fabric of the times for wet, cold and windy climates.

It was this relatively low, tech, high performance design that saw Flannel Shirts adopted for use by soldiers as early as the American Civil War through to now, frequently being sported by elite military units across the world.

Our latest interpretation of the Flannel Shirt sees the iconic plaid pattern recast in signature, muted ThruDark style with both Raven Grey and Olive Green variations.

Cut from midweight cotton to best balance insulation and comfort against performance, featuring two utility chest pockets and two hand warmer pockets. Designed with a point collar, button placket and long sleeves with buttoned barrel cuffs.
