Comfortable fabric and the underarm was not bulky which had concerned me prior to trying. I was hoping it would would be worth the investment as the items are not that cheap but hopefully it will last and be worth the investment

Perfect layering piece

Love that it's reversible (crew-neck or a low-ish V-neck) and can be layered to look like a T-shirt under a button-down or invisible under a sweater; also works well under a sheer top without distracting. I was worried it would be too small, but I ordered their suggested size, and it is a great fit for my purposes. If you want to wear it as a stand-alone tee, you may want to size up to get a more blousy effect. Love!

A Total Win

I am very pleased with The Signature! I was afraid I'd feel really hot wearing it, but I have not felt overheated. The material is breathable and allows fabric to move freely over it. My clothes do not cling or get bunched around it. Most importantly, it has kept my clothing clean and free of sweat stains. I plan on buying another one!

I can now wear shirts that aren't black!

Even with using prescription-strength anti-perspirant, I will have pit stains within an hour of putting on a shirt. Because of this, I have almost exclusively worn black shirts for years. But no longer! I bought two of these shirts to try out and can now go all day long with no pit stains! I even tried going on a long walk with a sweater on and did not sweat through it. These shirts are very comfy and are thin enough to be able to wear under another top without having visible lines. This shirt is worth every penny.

Comfortable and easy to launder

I like the fact that these shirts are very slim to wear as well as easy to launder (unlike some which need to be turned inside out otherwise the perspiration odor will remain with the shirt.) They feel sleek against the body. I also like the almond color.

Worth the high price. Definitely will be buying another. Fits nicely under most tops.

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.
