Why Wear An Undershirt?
Sweat stains? Expensive dry cleaning? Deodorant marks?
So many ways to save your clothes with one simple, comfortable, solution.
Meet the Essential Undershirt Collection.
Secret Sweat Shields
Each Essential Undershirt is enhanced with a discreet sweat shield in the underarm made from special sweat absorbing technical fabric.
This gives you extra sweat protection while keeping you dry and comfortable. And keeps your clothes clean longer.
Gentle on skin. Long lasting. Breathable.
TENCEL™ is a sumptuously soft fabric that regulates your body temperature, making it the perfect layering piece.

This was my first Numi purchase and I couldn't be happier! These undershirts are comfortable and really help extend the life of my clothes by reducing washing.

Underarm shields are well-made and beautifully-constructed. Unlike other products on the market, they are cut low in back and front and along the side of the collar so they don't peak through the overgarment.

Wow, this is the perfect undershirt - especially for purposes of preventing sweat stains!
Jaclyn G., Verified Buyer
I got this shirt because I use natural deodorants and they don't work as well as antiperspirant. This shirt protects my blouse and keeps me odor free.
Numi vs. Other Brands
Most undershirts on the market are designed for men. But women's clothing fits differently. Which mean women need a better fitting undershirt.
Unlike other undershirt brands on the market - whose undershirts have bulky sleeves, high necklines and sweat shields that make a weird crinkle sound - Numi's undershirts are made to be discreet, invisible and comfortable.
And with 8 different styles to choose from, we've got something to fit under everything.
