Kids UV Swimwear
Here at Trespass, we have designed Girls and Boys UV swimsuits and swimming costumes so that you can relax while your little ones make a splash! Babies' and children's skin is much more sensitive than adults's and can be affected by UV exposure a lot sooner. That’s why it is super important to protect them with sunscreen and UV swimwear. Our swimsuits are easy to remove, made with soft material for sensitive skin, and come in a range of fun and funky designs. Look out for the ‘UV Protection’ rating, which is marked on each of our kids’ swimwear products. Team up with a pair of aqua shoes or children's sandals for all-day fun and adventure.
