Underwear Trunks for Older Boys
Underwear trunks for older boys have a fitted short leg and an elasticated waistband, and the sizes here run for ages 8 to 15. There is no loose fabric to bunch under school trousers or jeans. Trunks suit long school days, PE lessons and weekend sports clubs, where loose boxers can ride up and briefs can feel too small for a growing boy.
Choose by height rather than age. A 10-year-old usually takes 146 cm and a 13-year-old 164 cm, but a tall boy may need the next size up. Trunks should sit close without digging in at the waist or leg, so go up if your son is between sizes. Some shops call this cut boxer briefs, which is the same close-fitting shape with a short leg. Check the product page and care label before the first wash.

Your questions answered
MINOTI's trunks for older boys are close-fitting underwear trunks with a short leg and an elasticated waistband for ages 8 to 15, in sizes by height in centimetres, with 158 cm usually fitting a 12-year-old.
What size underwear trunks should I buy for a 12-year-old boy?
Most 12-year-olds take 158 cm. Measure your son's height in bare feet and pick the size closest to it. If he sits between two sizes, go up for more room at the waist and leg.
How many pairs of trunks does a teenage boy need for a school week?
Seven to ten pairs is practical: one a day, plus spares for PE days and gaps between washes. Check his size each term, as a 14-year-old usually takes 170 cm and growth spurts come quickly at this age.
