The Bjorn Long Sleeve Linen Undertunic, also known as a traditional Cotta, is an essential foundation garment inspired by the clothing worn by both men and women throughout medieval Europe. Crafted from 100% woven linen, this versatile tunic is perfect for historical reenactment, Viking encampments, LARP events, Renaissance fairs, and living history displays.
Made from breathable natural linen, a staple fabric for both everyday peasant clothing and noble undergarments, the Bjorn Undertunic delivers comfort, authenticity, and practicality. Its classic design features a modest slit neckline and long, narrow sleeves, allowing it to fit comfortably beneath a wool overtunic, heavy surcoat, armour, or cloak.
A prominent central riding slit at the hem enhances mobility, making it easier to walk, work, or ride horseback without restriction. Historically, garments such as this would be worn belted at the waist with a sturdy leather belt, creating a functional silhouette while providing a place to carry pouches, tools, or a utility dagger.
For an authentic medieval appearance, wear the Bjorn Undertunic beneath a colourful wool overtunic or contrasting kirtle, allowing the linen collar and sleeves to remain visible in traditional fashion.
Whether worn as a practical base layer or as part of a complete historical outfit, the Bjorn Long Sleeve Linen Undertunic is a timeless addition to any medieval or Viking wardrobe.
