Heading off on holiday? Our boys' red shorts will keep him feeling cool in the heat. Explore our bright selection of swimmers so he can make a splash at the local pool or be easy to spot on a crowded beach. You'll notice lined red swim shorts for boys with fast-drying fabrics and elasticated drawstring waists that keep them comfortably in place. Some are available as matching vest and shorts sets that can be worn as separates. And of course, these shorts aren't just for summer. We've also got boys' red jersey shorts that are ideal for adventures in the park. As a bonus, relaxed fits make pairs well suited for sports and general running around. Team them with a printed t-shirt and some trainers or sliders for the perfect summer outfit. If temperatures drop, a hoodie will keep him warm 'til home time.
