Swim Shorts & Rash Vests for Every Adventure

Our boys’ collection includes quick-dry swim shorts, graphic designs, and long-sleeve rash vests crafted with UPF 50+ fabrics to shield against harmful UV rays. Whether he’s learning to swim or enjoying a family trip, these pieces deliver confidence and comfort in and out of the water.

Mix & Match Summer Essentials

Pair his swimwear with easy holiday looks from our boys’ T-shirts & polo shirts and lightweight shorts for all-day comfort. For evenings by the pool, layer with cosy picks from our nightwear or casual footwear.

Designed for Comfort & Play

Every swimsuit and rash vest is built to last, with stretch fabrics that move with him and bold designs he’ll love wearing. Elasticated waists and easy fits make getting ready for the water simple, while bright colours and fun prints add an extra splash of personality.
