Prevent Sweat Stains

Stay Fresh, Confident, and Stain-Free All Day.

Numi’s Solution

Essential Undershirts

With built-in sweat-proof underarm shields, they ensure you stay dry and confident all day without worrying about embarrassing stains.

How to Style

Stay fresh in our Essential Undershirt — perfect under a crisp blouse or blazer for work, or layered under scrubs, tees, or casual outfits for BBQs and brunch. Keep cool and confident, no matter the day.

"Love my Numi! They're very comfy and thin enough to use without feeling too bulky. Keeps things fresh, stretches out the wear of garments. I wash in the machine and hang dry without any issues."

Evie

"I am so glad I found out about Numi undershirts! With this undershirt on, my sweat is fully absorbed and my armpits still feel dry. Now I can go back to wearing shirts I had written off before."

Karin

"Loved it! I am a personal stylist and so many clients are dealing with the heat and sweating through their tops. This is such a great solution! I tested this out for myself and LOVED it. It absorbed sweat, it was smooth and the square neckline was flattering! "
