Frequently Asked Questions

How is Numi Merino Wool different from other merino wool tops?

Unlike other merino wool tops, our Numi Merino Wool collection is 100% Australian Merino wool with built-in Contemporary Cotton™ underarm shields for effective moisture-wicking and sweat protection. Our Merino Wool fabric is lightweight and breatable to keep you cool and dry, all day.

Is Merino Wool line machine-washable?

Our Merino Wool Undershirts are machine washable: simply wash them on the Wool Setting. If your machine doesn’t have that setting, use Cold Water Wash or Delicate Wash Cycle. Spin, do not tumble dry. We recommend flat drying garments after washing.
