FAQ

Sweat-Proof Undershirts: Your Questions, Answered.

Sweat proof undershirts are made of contemporary cotton with a unique underarm garment to prevent sweat stains from showing on the outer clothes. Our undershirts are made with moisture-wicking fabric that absorbs sweat and keeps you feeling dry and comfortable.

Make sure to check our sizing guide on the product page, next to the sizing choices. You can also take our sizing quiz to find the right size for you. If you’re still unsure, chat with us (pressing a chat box on the bottom left part) or send us an email at customercare@wearnumi.com.

Our undershirts are machine wash cold, tumble dry low. Please wash with like colors.
