FAQs

Why do I need an undershirt?

Women need sweat-proof undershirts to prevent visible sweat stains on their clothing and to stay dry and confident throughout the day. It can also help prolong the life of outerwear by reducing the need for frequent washing.

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.

How do I find the right size?

We recommend using the size guide (featured on every product page) to determine the best size for you.

Each size guide features a sizing chart and instructions on how-to-measure the item. Generally, we recommend ordering our Merino Wool Undershirt collection in your regular size for the perfect, snug fit. If you prefer a more relaxed fit, we recommend sizing up. If you’re still unsure about sizing, send us an email at customercare@wearnumi.com.
