For the Lasse medieval vest, made of 100% cotton, a washing temperature of 30 to 40°C is recommended to prevent shrinkage of the natural material and fading of the brown color. Before washing, the vest should be turned inside out and all buttons and lacing should be closed to protect the fabric. After washing, it is recommended to gently reshape the garment and allow it to air dry. A splash of vinegar in the rinse water can help keep the fibers supple.
