Mizu Smart Bath Towel is a spa-quality, Japanese artisan craft that has the power to detect impurities. It features color changing strips that identify residual contaminants including soap, sweat, and dirt. The mix of Xinjiang cotton and pure silver make it one of the softest towels with the power to inhibit 99% bacterial growth. Plus, the twisted yarn weaving gives it maximum durability. With a size of 56” by 30” it dries three times faster than your regular towels and can hold five times its weight in water. The towel is the epitome of the Japanese crafting techniques.
