【BPA-Free Hot & Cold Collapsible Bottle】This collapsible sports bottle has a food-grade silicone body and a PP lid. It is 100% BPA-free, safe and healthy for daily use. Featuring a unique dyeing process that is harmless to the human body, it combines good looks with safety. It works for both hot and cold drinks, with a temperature range of -13°F to 392°F.Note: Silicone does not have heat insulation. Please do not hold the bottle body directly when it contains hot water to avoid scalding. We suggest cleaning it with boiled water or a lemon before using it for the first time. 【Ultra-Light Collapsible Silicone Water Bottle】This water bottle boasts a 16-ounce capacity and weighs only 6.0 oz. It has a 2.75-inch diameter—expanding to 8.85 inches tall when in use, and folding down to 5.11 inches tall for a compact profile. It fits easily into backpack side pockets, gym bags, or even your pants pockets. Perfect for hands-free carrying on hikes, camping trips, or short getaways without taking up extra space. 【Detachable Wide-Mouth Easy-Clean Water Bottle】The bottle body and mouth feature a detachable design, expanding to a 5cm-wide opening when separated. You can easily add ice cubes, lemon slices and other mix-ins, and enjoy smooth, spill-free pouring. What’s more, the wide-mouth structure paired with detachable parts lets you reach every corner—inner walls, mouth gaps and beyond—for thorough residue removal and fresh use every time.
