FAQs

Frequently Asked Questions

What is a sweat-proof undershirt?

A sweat-proof undershirt is a type of undershirt designed to prevent sweat from showing through outer clothing. Our undershirts contain moisture-wicking properties and sweat-absorbing underarm pads.

How does it work?

Each Essential Undershirt is enhanced with a Contemporary Cotton shield in the underarm. This gives you extra sweat protection while keeping you dry and comfortable, and keeps your clothes clean longer. 

How do I wear an undershirt?

Our undershirts are meant to be worn as a base layer underneath your outer clothing. Our sweat-proof undershirts are specifically designed to be worn under other garments to provide a layer of protection against sweat stains. We recommend layering your undershirt under sweaters, blouses, or any other top layer to prevent visible sweat stains from showing through onto your clothes. By wearing an undershirt, you can stay dry, comfortable, and confident throughout the day.
