Worth it!

I can finally wear my fine fabrics without worrying about perspiration marks showing or staining. AMAZING product. It's expensive but worth it. I gave it 4 stars instead of 5 just because the padding under the arms can get bunched up and become a little uncomfortable, and I wish the fabric was more breathable, but I'm still really happy I bought it.

Great undershirt!

This shirt matches my skin tone fantastically and works very well as an undershirt, even under boatneck tops.

BEST wardrobe investment ever

Absolutely love the Numi Signature undershirt. It’s an investment I should have made a long time ago! The product delivers on its promise of protecting shirts from sweat marks and deodorant stains. The fit is snug and the sleeves are seamless, making it easy to wear under tighter-fitting blouses. The fabric is a bit see-through, but I don’t mind too much, as I wear it underneath my shirts. Definitely recommend!

Yup, I will buy more

I'm not a boardroom exec thankfully even though I own several companies, so the sweat thing was not why I was buying these. I bought these because I go through different energies for lack of better wording. There are times when I need to feel a second skin around my body. Now over 50, wearing skin tight anything - nope not built for that anymore. But I wanted to feel that layer close to my skin. I also like these because i can wear them under clothes and don't need a bra, there is no support though. It would be nice if the weave lent itself to a bit of support. the one thing i did not like, was the white one, had nude underarm pads, that that makes them stand out. They should be white. And the length is way too long. the shirt goes pass my butt, a bit of pain tucking into pants.

LOVE these tops!

I purchased 2 of The Signature tops (one in nude, one in white), and I am impressed!

I walk an hour each way to work, so I bought these tops with high hopes as the summer weather has been hitting us hard.. and I have to say, they do not disappoint! I also work as a physiotherapist, so I am constantly moving and teaching exercises. I was so impressed when I came home the first day after wearing my Numi top, and there was NO SIGN of any sweat!

The only reason I took off 1 star is because the white top is quite sheer so any non-nude bra is just not an option to wear underneath, which is a shame because I actually love the fit and look of the white top and would love to be able to wear it as a standalone piece as well as an undershirt.

About Numi

Numi was born out of personal necessity. One day our founder, Michelle, realized she never wore her favorite clothes. They were either prone to noticeable sweat stains or expensive to dry clean. When she looked for a solution, there was nothing available. And so Numi was born.

Numi is a brand that celebrates what it means to be a woman. We make consciously created products that make life a little easier for us all and inspire a culture of kindness.

Committed to Sustainability

Being mindful of our impact has always been at the core of what we do. We like to think of it as a living commitment that grows and evolves with us. This year we're taking it further. We are in the process of auditing ourselves to see how and where we can be kinder to the planet.
