Medieval Linen Shirt – Authentic A-Cut Undershirt Historical Base Layer

In the medieval world, the linen shirt formed the foundation of every wardrobe worn daily by peasants, craftsmen, and knights. Long before cotton became common in Europe, linen, woven from the tough fibers of the flax plant, was prized for its durability, natural coolness, and moisture-wicking ability. It allowed the skin to breathe, absorbed perspiration, and dried quickly making it ideal for both laborers in the field and warriors in armor. Archaeological finds from across Europe confirm that linen was the true underlayer of medieval clothing, valued for its practicality and comfort, and remains the most authentic choice for historical reenactment today.

Our “Waldemar” Medieval Linen Shirt continues this timeless tradition, offering the same breathable, lightweight comfort that medieval people depended on. Made from 100% pure linen, it’s perfect for hot weather and long hours of wear, providing a cool, airy feel even under heavy outer garments. The fabric’s natural texture gives it an authentic look and a satisfying hand-feel that grows softer and smoother with use.

For those who prefer a slightly softer and more versatile option, we also offer the linen-cotton blend (87% cotton, 13% linen). This version combines the strength and crisp texture of linen with the gentle softness and flexibility of cotton, creating a fabric that’s easier to maintain and slightly less prone to wrinkling. It’s an excellent choice for those seeking everyday comfort while retaining the historical appearance and breathability of natural fibers.

Whether worn beneath armor, gambesons, or padded coats, or simply on its own, the Waldemar Linen Shirt offers both authentic medieval realism and modern practicality.
