QUESTIONS & ANSWERS ?Q: What's the material of water bottle? A: Non-toxic & BPA free Tritan. Tritan is Non-toxic & BPA free materials for infants and young children in the United States. ?Q: Why the water bottle will sweat after filled with ice water or put in ice cubes? A: Because the bottle is relatively cold at this time, the water in the air will be adsorbed on the bottle and condensated into water droplets, and when the water droplets accumulate enough, it looks like sweating. This is a normal physical phenomenon. ?Q: Why the full-water bottle will be cracked after a overnight freezing? A: Because when the water freezes into ice, the volume becomes larger. And when the water freezes, it begins to freeze from the upper layer, so there is not enough space for the ice below, lead to the bottom of bottle will be split by ice. So we don't recommend you freeze the full-water bottle. It is recommended that you add ice cubes to the bottle if you need cold water.
