What's so special about this bottle? As you drink your beverage, you can adjust the bottle size. Drink a little - Collapse a little. A fashion-forward, stylish silicone water bottle with a stainless steel lid. The large opening allows you to toss ice cubes into the bottle, but if you prefer hot liquids, you can totally do that too! This water bottle can withstand liquids up to 450°F (230°C) - no burning, no melting.
