Boys' Briefs for Ages 2 to 8

Briefs are the close-fitting style of boys' underwear, cut higher on the leg than trunks, and the sizes here suit ages 2 to 8. They sit flat under school trousers, joggers and shorts, so there is less bunching when a boy is dressing himself. The range suits children who are out of nappies and need a drawer of everyday pairs for nursery, school and weekends.

Choose the size by your son's height rather than his age. A 4-year-old usually takes 110 cm and a 7-year-old usually takes 128 cm. If he sits between two sizes, go up one so the leg openings do not dig in. For fabric and washing details, check the product page and the care label. Socks and other underwear styles sit in the wider Underwear & Socks section.
