This insulated water bottle boasts excellent insulation performance with its double-walled, sweatproof design. Crafted from high-quality, food-grade stainless steel, it maintains drink temperatures for hours without altering taste. Testing indicates temperatures exceeding 113℉ for hot beverages after 24 hours and remaining below 50℉ for cold beverages with ice after 48 hours. The bottle is constructed with BPA-free 18/8 stainless steel, complemented by PP material for the lid and straw. Featuring a wide, sturdy handle and a leak-proof lid, it offers versatility with two drinking options: a straw or spout lid. The spout mouth’s extra-wide opening facilitates easy filling, drinking, and cleaning, making it ideal for outdoor activities like camping and hiking. Usage tips include washing before use, avoiding dry ice, and refraining from microwave and dishwasher use (except for the stainless steel color). Additionally, the product comes with an 18-month guarantee covering replacements for faults caused by non-artificial reasons.
