A stomach over the waistband and underwear that stays put

Short answer: Choose a wide, soft waistband and a style with a high back. The band should sit either below the stomach or well above it, never across the middle.

Where the waistband should sit

If the band sits across the middle of the stomach, it rolls down every time you sit. Two positions work. Either below the stomach where the hip holds it, or above the stomach where there is less movement. Try both and see which stays.

Width makes the difference

A wide band spreads pressure over several centimetres and does not cut. A narrow elastic gathers all the pressure in one place and leaves a groove. It is the single most important detail. See bamboo underwear briefs for men.

There has to be enough fabric at the back

If the back is cut too low, the band is pulled down at the back and up at the front. Choose styles with a higher back, often called high back or comfort fit. See bamboo underwear for men.

Size by the widest point

Measure where you are widest and choose by that. Sizing down to tighten the band only makes it cut more. See bamboo clothing for men.

Frequently asked questions

Will a larger size not just be loose

No, if the style contains elastane. Then it follows the body without pinching.

Are boxer shorts better than trunks

Often yes, because the band is wider and the back is cut higher.

Why does the band only roll when I sit

Because the stomach takes up most room in that position and pushes the band out of place.
