No need for high temperatures or special detergents because merino is self-cleaning in water and naturally releases dirt and odor even in a cool wash. Simply wash at up to 100F (40C) with all your other clothes using your usual detergent.
Your lightweight garment will line dry quickly or you can just leave it out overnight. If pushed for time, you can tumble dry on low heat, but do so sparingly and you will prolong your garment's life.
After washing, merino recovers its shape without wrinkling. You should never need to iron it, but if you want to, use the wool setting.
Treat it with respect and your trusty Armadillo Merino® garment will give you years of loyal service. When the time comes to say goodbye, don't just throw it away, bury it with honors. As a protein, merino fiber biodegrades in the soil within 12 months while releasing valuable nutrients and in doing so, completes the natural cycle.
