The Sweat Stomping™ Undershirt is designed for layering, not for stand alone wear. That means a closer cut that helps it stay flat, stay hidden, and stay in place.

If you’re between sizes, we recommend choosing the smaller option. A trimmer fit reduces bunching under a dress shirt and keeps lines clean.

Care:

For best longevity of your undershirt machine wash cold using a gentle detergent. Avoid bleach. For best results, hang dry or tumble dry low. No ironing necessary. Like most frequently used garments, the Sweat Stomping™ Shirt will eventually show signs of wear. We recommend assessing every 6–12 months, depending on frequency of use. If the fabric begins to lose its stretch, the fit softens, or seams start to fatigue it’s time to rotate in a fresh one.
