Bjorn Linen Undertunic (Cotta) – Black | Medieval & Viking Historical Base Layer

The Bjorn Linen Undertunic, also known as a traditional Cotta, is a timeless garment inspired by the foundational clothing worn throughout medieval Europe. Suitable for both men and women, this handmade tunic serves as an authentic base layer for historical reenactment, Viking encampments, living history events, LARP, and Renaissance fairs.

Crafted from 100% woven linen, this practical garment reflects the everyday clothing worn by peasants and the comfortable underlayers favoured by nobility. The lightweight, breathable fabric makes it ideal for long days at events, while its versatile design pairs effortlessly with overtunics, surcoats, kirtles, and other period attire.

The tunic features a modest slit neckline and short, narrow sleeves, allowing it to sit comfortably beneath heavier garments. A central riding slit at the hem enhances mobility, making walking, working, and horseback riding more comfortable without restricting movement.

For a complete historical appearance, wear it with a sturdy leather belt to gather the fabric at the waist and carry period accessories such as pouches or utility knives. Layer beneath a colourful wool overtunic or contrasting kirtle to recreate an authentic medieval look.
