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 the sweat-absorbing underarm pad work?

Each sweat-proof undershirt features a sewn-in gusset, a one-way moisture transfer system that absorbs moisture away from the body while preventing it from moving through and staining the outer garments.

Our technology is embedded at the yarn stage, which means it won’t wash out and will last the life of the garment.


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 sweat-proof undershirts are meant to be worn as a base layer underneath your outer clothing 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.
