Mens Underwear Size Chart– Our Briefs and Boxer Briefs are Sized to Fit a Man’s Waist


This size chart will help determine the correct size to order for your style and color preference. UFM Underwear offers sleek, streamlined tailoring. Our sizing is measured by your waist measurement, just like sizing for men’s pants. This means you get a waistband that fits and doesn’t ride up or down. Underwear For Men are made to move with you!

How To Measure Your Waist: Measure around your natural waistline—right above your hips. Be careful not to squeeze too tight to allow a little give. All of our size measurements are in inches.

Underwear For Men Briefs and Boxer Briefs

Our company designs briefs and boxer briefs, both of which have UFM’s US patented and Intl patents pending adjustable pouch. You simply tie the drawstrings of the pouch, and you get your preferred level of support. Most guys choose between the ‘high and tight’ or the ‘low and light’ option for their activities. You don’t need to change pairs of underwear throughout the day, simply tie to your preference and go. As mentioned, our mens underwear fits into the following categories:

Moisture Wicking Material Keeps You Cool

No matter what you are doing or where you are going, moisture wicking material for your men's underwear is always a good idea. Our brand is made with moisture wicking materials to keep you cool and free of sweat. Underwear For Men briefs and boxer briefs are commonly worn for working out, swimming, enjoying time with friends and family, going to work, recovering from medical conditions, going to the office, doing yard work, and more. Thanks to the moisture wicking material, you won’t need to change pairs of underwear for different parts of the day.

Check Out Our Big and Tall Sizes

Are you tired of the standard sizing for men’s underwear? When you purchase UFMs, you always know you are getting the right size for your body because of the waist measurement. We now sell Big & Tall sizes for guys with larger waist measurements. Our brand is able to accommodate up to a size 5X, or a 58’’ waist.

In addition, we offer a longer inseam length of 9 inches for guys that prefer longer boxer briefs. This is advantageous for men with larger or more muscular legs. The tapered leg design of our mens underwear stays in place on even the most muscular guys. We know this is a hassle for athletic men and eliminated the issue by creating a boxer brief that moves with your body.
