Our Boxer Briefs are designed to fit close but not tight or restrictive. If you are between sizes, the smaller size will fit better if you wear slim or tailored-fit pants and prefer a snug fit. If you prefer a looser fit, pick the larger size. To measure, run a tape measure around your waist. Place one finger between waist & tape & measure for a comfortable fit. You can also use the first number on your Jean size as reference.
Please check out our full Measurements Chart (PDF) to see specifics on dimensions for each size.
