Wavy Black and Green Pattern 1000ml Double Walled Stainless Steel LeakProof Sports Bottle Thermo 8h Portable

This premium double-walled stainless steel sports water bottle is designed for long-lasting heat and cold retention. Made of food-grade 304 stainless steel, the bottle features a vacuum-insulated double-layer construction to keep drinks hot for up to 6 hours (65°C) or cold for 8 hours. The exterior is crafted from durable stainless steel, and the interior includes an insulated layer to enhance thermal performance. The leak-proof straw lid with a vent valve ensures smooth drinking and easy one-handed operation. The straw and lid are made of food-grade PP and silicone, ensuring safety and durability. A wide ergonomic handle allows for comfortable single-handed carrying, while the collapsible straw design makes it easy to store. The bottle is fully disassembled for easy cleaning with mild detergent and warm water. To maximize insulation, preheat the bottle with hot water or pre-cool it with ice water before use. When using hot drinks, avoid filling the bottle to the brim to prevent spills. Always tighten the lid securely when tilting the bottle. Do not place the bottle in direct heat, microwaves, or dishwashers, and avoid storing acidic liquids like soup or soy sauce to prevent corrosion. The bottle is suitable for hot/cold beverages and ideal for gym workouts, outdoor activities, or daily office use.
