Please do not size up - these are already generous, even when worn over lots of layers.
Wash on a 30°C wool wash cycle. Many machines have a hand-wash wool cycle. Please use a detergent designed for wool such as our wool shampoo (see "essentials" category). But you'll seldom have to wash this - you will find that dirt somehow disappears as little scales on each wool fibre shrug off dirt amazingly successfully! Truly self-cleaning.
This lovely 100% organic Merino wool body warmer is ethically and expertly made by Disana in Germany.
