Icebreaker recommends a cold machine-wash with like colours before wear and line dry in shade. Machine wash warm. Wash inside out with like colours. Do not use softeners. Fasten all closures to wash and dry. Do not bleach. Do not tumble dry. Line dry in shade. Warm iron. Do not iron print, trims and accessories. Do not dry clean. Merino is super lightweight, soft, non-itchy, non-clammy, warm in the cold and cool in the heat, and has a miraculous ability to resist odour. Because it was made in the mountains rather than in a petrochemical laboratory. Merino wool fibre is naturally renewable, recyclable and biodegradable*. *wool tops, under certain conditions
