Contemporary Cotton

Contemporary Cotton is a high-performance moisture management system that moves moisture away from the body.  It keeps you cooler and drier.  And washes clean of odors.  Each Essential Undershirt is enhanced with a Contemporary Cotton gusset in the underarm. This gives you extra sweat protection while keeping you dry and comfortable. And keeps your clothes clean longer.

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.
