Our story
Have you ever avoided wearing some of your favorite outfits because they are prone to embarrassing sweat stains? Or been fed up with the high cost of dry-cleaning?
Me too. When I was working in finance, I faced these challenges every single day. Until one day I decided to do something about it. And that's when I came up with the idea for a sweat-proof undershirt that would be invisible under my clothes and keep them clean longer.

Hallie D.
"This is the perfect solution for eliminating sweat stains. I only use deodorant and was ruining tons of tops. I can already tell a difference in my clothes. I wear this every day."
Stacey W.
"These undershirts are truly amazing. They are so comfortable and have saved my blazers. Normally I can wear a blazer once before I have to clean it, but with Numi undershirts I can go several wears before cleaning. I absolutely cannot recommend them enough."
Nems W.
"I'm obsessed with these undershirts. They really do work and are so comfy! I just spent the holidays practically living in them and have ordered multiple more -- game changer!
