Customer Reviews
Definitely no sweat stains. Light as a feather feel, you'll forget you have it on.
This undershirt is amazing. Hands down. Not only does it stop sweat stains, but it prevents you from feeling sweaty, and in turn stops smells.
I was shocked by how well these work! I feel dry while wearing them, sweat does not soak through the under arm area and they keep me feeling cool.
