Men's Boxer Brief Size Guide
Boxer briefs are simple until they're the wrong size.
Too tight, and your day is ruined before lunch. Too loose, and everything starts moving like it has somewhere better to be.
Here's how to get it right.
How to Measure
Measure around your waist, just above the hips and below the belly button.
Use a soft tape measure. Keep it snug, not strangling. Measure against skin, not over jeans, shorts, or whatever you're pretending still fits.
Size Chart
| Size | Waist | Fit |
|---|---|---|
| M | 80 – 88 cm / 31" – 35" | 7-inch boxer brief |
| L | 88 – 96 cm / 35" – 38" | 7-inch boxer brief |
| XL | 96 – 104 cm / 38" – 41" | 7-inch boxer brief |
| XXL | 104 – 112 cm / 41" – 44" | 9-inch boxer brief |
7-Inch Boxer Brief
Available in M, L, and XL.
This is the everyday Unluckies fit: mid-length, soft, breathable, and made to stay in place without feeling too long under clothes.
Best if you want a clean boxer brief fit with enough coverage, but not a full long-leg style.
9-Inch Boxer Brief
Available in XXL.
Same Unluckies feel. Longer leg.
The XXL is cut as a 9-inch boxer brief for more coverage, a fuller thigh fit, and less ride-up through the day.
Best if you want extra coverage or usually find boxer briefs riding up your thigh.
Between Sizes?
Order your usual waist size.
If you're between sizes and like a secure fit, go down. If you prefer more room at the waist and thigh, go up.
Unluckies are soft and stretchy, so don't size up unless you actually want the extra space.
How They Should Fit
Unluckies should feel secure, not tight. They should sit flat at the waist, cover properly at the back, and stay close through the thigh without squeezing.
Basically: no digging, no bunching, no mid-day rescue mission.
If they feel loose around the leg or seat, you probably need one size down.
Fabric
Made from soft MicroModal with stretch — smooth, breathable, and easy to wear all day.
Wash cold. Air dry or tumble dry low. Don't iron. Don't bleach. Don't punish them.
