Manufactured in sunny California, all of our suits are made with UPF50+ fabric that blocks out 98% of UVA and UVB rays! Many other companies design their suits with a UPF50 chemical that will eventually wash out over time, but because our UPF50 is built into the weave of the fabric, you can wash your Tutublue suit as many times as you need without the protection diminishing over time. Every Tutublue suit is also engineered with Quick Dry Technology and 4-way stretch, making them gentle on the skin, breathable, lightweight, and swim-friendly. Tutublue products have been approved by the American Melanoma Foundation and the Melanoma International Foundation.
