The difference between boxers and boxer briefs comes down to fit. Boxer briefs are form-fitting and snug around the legs, whereas boxers offer a looser fit on the legs. For more information, check out our Fit Guide.

Boxer briefs are designed for support and a snug fit. That being said, your boxer briefs shouldn’t feel too tight. The ideal boxer briefs keep your package in place without constricting anything. Your inseam length (the measurement from one’s crotch to the bottom of one’s leg seam) can help you figure out if boxer briefs are for you. Pair of Thieves boxer briefs have a 5” inseam. If you prefer a shorter length, check out our trunks. If you’re looking for something longer, take a look at our long boxer briefs..

Start by checking the size of the underwear you're currently wearing. Then measure your waist with a tape measure. Compare your waist measurement with the Pair of Thieves sizing breakdown on our Fit Guide.

If boxer briefs are your usual go-to, we recommend purchasing enough to have 10-12 fresh pairs at your disposal. If they’re more for occasional wear, 3-5 pairs should suffice. You should ideally own 15-20 pairs of underwear total. How you choose to meet that man-panties quota is totally up to you.
