From the new O'Neill range, this ruby blue UV rash T-shirt for girls offers UPF 50+ sun protection. In a cool ruby blue, with a funky O'Neill print on the front, this short sleeve O'Neill girls rash tee is perfect for wearing over a swimsuit or bikini when swimming, sailing or under a wetsuit.

Sizing note: these are designed to be very fitted, for when worn under a wetsuit. So we recommend going up at least one size when intending to use over normal swimwear.

Fabric composition: 92% nylon/8% elastane – quick drying.

All swimwear must be rinsed in fresh water after use – this will significantly extend the life of your swimwear. Bright colours will fade, this is considered normal wear and tear.
