Frequently asked questions
How do I choose my boxer size?
Waist measurement at the narrowest point (where the belt sits) gives the reference. 82-86 cm = M, 87-92 cm = L, 93-98 cm = XL. For a tight fit, take your exact size; for comfort, size up.
Difference between boxer, briefs and slip?
Boxer hugs thighs and reaches mid-thigh. Briefs are wider and let the crotch breathe. Slip is short and covers only the intimate zone. All use the same S-XXL grid.
US vs FR size correspondence for boxers?
A US M boxer corresponds to FR M in most brands. But US uses 30-32 (in) and FR uses cm or letters. W32 US = FR 42 = M usually. Always check the brand chart.
Does stretch cotton allow sizing down?
Yes, stretch cotton (5-10% elastane) allows one size down for a very close fit. 100% non-stretch cotton requires exact size or larger if you like comfort.
How long does a boxer last?
Quality boxer lasts 12-18 months of regular use. End of life: loose elastic, thin/holed fabric, faded color. Renewing 4-6 basic pieces yearly is a good budget/hygiene compromise.
