The Ralph Lauren Boys' Cotton Stretch 3 Pack Boxer Shorts Set in Grey is a set of three everyday boxer shorts in a mid-grey colourway, made from 95% cotton and 5% elastane and manufactured in Sri Lanka. Grey is the most practical neutral in boys' underwear — it hides everyday marks more effectively than white, doesn't show under light-coloured clothing the way black can, and reads as a clean, unfussy choice across the full age range this set covers.

The cotton stretch composition delivers the softness and breathability of cotton with the shape retention that elastane adds — a combination that matters for boys who are physically active throughout a school day or spending long stretches in casual wear. Three pairs in rotation means each pair washes and dries between wears, maintaining condition better than a single pair or two used continuously.

The set carries a sustainability credential and features across the Stocking Fillers, Gifting, Loungewear, Back to School, and Casual collections at Childsplay Clothing. For parents searching for designer boys' grey boxer shorts, a Ralph Lauren cotton stretch underwear set, or a boys' sustainable underwear gift, this covers multiple briefs with a single purchase.

Care tip: Machine wash at 30°C — grey cotton is one of the more forgiving colourways to care for, as it doesn't show the yellowing risk of white or the lint attraction of black. The elastane content is best preserved at lower wash temperatures; high heat degrades stretch fibres over time and causes the waistband to lose its snap. Air dry or tumble on low. Do not bleach.

Size guide: The range spans ages 6–8 (smallest bracket) through M, L, and XL for older boys. Sizing runs broadly true to age — for boys at the wider or taller end of any bracket, size up at the transition point for a more comfortable fit.
