The White Rock Oasis X-Lite Micro-Fibre Hat is a soft, lightweight unisex hat which features Hydro Cool crystals in the headband. The Unique crystals are sewn into the inner headband area, when you feel the need to cool down you simply soak the front section of the headband in water for about three minutes. The crystals absorb the water and provide a cool and comfortable sun hat. The hat, which has a UPF of 50+, also features a security pocket hidden in the crown, Bug Off treatment to help repel insects, and they are water and stain resistant thanks to their Teflon coating.
