The Ralph Lauren Boys' Cotton Stretch 3 Pack Boxer Shorts Set in Black is a set of three everyday boxer shorts in a versatile black colourway, made from 95% cotton and 5% elastane and manufactured in Sri Lanka. Black is the most adaptable colour in the underwear drawer — inconspicuous under any clothing, appropriate across every occasion from school uniform to casual weekend wear to sports kit, and the colourway that requires the least thought in the morning routine.

The cotton stretch construction balances natural breathability with the shape retention that elastane provides — the 5% elastane component keeps the waistband and leg openings from loosening over time, which matters across the extended size range this set covers. With sizing running from age 8 through to 18–20 years, this is one of the few boys' underwear sets in the Ralph Lauren range that genuinely bridges the gap between older juniors and young adults, making it relevant for a wider buying window than most kids' basics.

The set carries a sustainability credential and features across Stocking Fillers, Gifting, Loungewear, Back to School, and Casual collections at Childsplay Clothing. For parents or older boys searching for designer boys' black boxer shorts, a Ralph Lauren underwear set for teens, or a sustainable cotton stretch boxer 3-pack, this is a well-specified option that works from primary school age through to sixth form and beyond.

Care tip: Machine wash at 30°C — black cotton is susceptible to fading if washed at high temperatures or with harsh detergents, so a cool, gentle cycle is essential for maintaining the depth of colour over repeated washes. Wash inside out to reduce friction on the outer surface. Do not tumble dry on high heat. Do not bleach under any circumstances.

Size guide: S fits age 8, M fits ages 10–12, L fits ages 14–16, and XL covers ages 18–20. The upper brackets extend into young adult territory — boys at the XL end of this range may find it useful to compare against Ralph Lauren's adult sizing for the best fit.
