Choosing the Right Size

The recommended size on the chart will provide a light body hugging fit. If you prefer a slightly looser fit, choose a size larger. The shirts are not compression shirts, but do provide a close to the body feel.


“Gotta tell you, it’s a very nice product. Good fit, good feel, good price. Comparatively, the UnderFit fits and feels very close (or as nice as) to the more expensive micromodal/lycra undershirts that are priced in the $30+ range.”
“If there is a better purpose-built undershirt out there, we have yet to find it.”
“No rising, No billowing. We managed to get through a whole day without a single untuck from under our made-to-measure shirts.”
The Gents Staff
“The problem with most undershirts is that they’re just T-shirts. UnderFit’s shirts are made from lightweight yet durable fabrics with a touch of stretch and are designed to be worn under your shirts.”
