Our UV t-shirts are made with a material called PBT. This material is already used in high end sportswear because of it's extraordinary properties. Konfidence is leading the way in using the benefits of this material in the design of its children's UV clothing. When you compare PBT to Lycra, it is proven to retain its shape for longer, which means it snags less and is a far more chlorine resistant t-shirt. Because of it's ability to maintain it's shape, it is able to provide greater consistency in its UV protection rating over the life of the t-shirt. Making this wonder material perfect for whatever your little ones get up to. With colour changing logos to show you the impact of UV, you can rest assured your little ones will be safe.
