"I wish I bought one of these earlier! Great fit, very comfortable and the fabric is soft. Was able to wear my work dress with confidence that I wouldn’t sweat through. Worked amazingly well and I’m excited to bring out some of my shirts I’ve avoided wearing for fear of sweat marks."

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.

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.

This undershirt is incredible!! My silk and cotton blouses worn over top, as well as wool sweaters - basically everything that you cannot easily wash, and certainly cannot wash in a machine - now need to be washed maybe once in five wears, if that even. The undershirt is quite seamless, well-designed in its shape and fabric, breathable, reversible back to front for different neck lines, the pit pads would be noticeable if you wore it without some thing over top, but if you wear something over top they are not noticeable at all. I’m not like a super sweaty person, but I am moderately sweaty and I gotta say these undershirts are the best for containing it, while I am at the office or out and about and wearing some thing that I absolutely do not want sweat stains to show on.

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!
