The Ralph Lauren Boys' Cotton Stretch 5 Pack Boxer Shorts Set in Blue is a set of five everyday boxer shorts in a classic blue colourway, made from 95% cotton and 5% elastane and manufactured in Sri Lanka. The 5-pack format is the primary differentiator here — five pairs in a single purchase covers a full school week of underwear without any repetition, which is the practical calculus most parents are working with when buying boys' basics at the start of a new term.

The cotton stretch construction — 95% cotton for breathability and softness, 5% elastane for shape retention — is well-suited to the Back to School context. Boys in school uniform are typically active across the full day, and underwear that holds its shape rather than bagging out by mid-afternoon is a practical advantage over pure cotton alternatives. The blue colourway is neutral enough to work under any colour of uniform or casual clothing without concern.

For parents searching for a Ralph Lauren boys' boxer set, a 5-pack boys' underwear set, or a designer Back to School essential that combines brand quality with genuine everyday practicality, this is one of the most complete single purchases available in the Ralph Lauren kids' basics range.

Care tip: Machine wash at 30°C to preserve both the cotton's softness and the elastane's performance. The 5-pack format means each pair goes through fewer wash cycles per week than a smaller pack would — five pairs worn in rotation wash less frequently and maintain their quality longer than a 2 or 3-pack on the same rotation. Do not tumble dry on high heat; air dry or low tumble. Do not bleach.

Size guide: S fits ages 6–8, M fits ages 8–11, the 11–14 Yrs bracket covers older juniors, and XL fits ages 13–15. For boys who are tall or broader in build for their age, sizing up at the transition points is the better approach. At the upper end of the range, it’s worth comparing against Ralph Lauren’s adult small if your son is already in adult sizing in other categories.
