20 oz adult insulated water bottle

Our 591 ml sports water bottles are made of food-grade 304 stainless steel, which is non-toxic, environmentally friendly, and durable. The BPA-free sliding lid can effectively prevent water leakage, making it safe for daily consumption.

Double-wall insulation: This can help your hot drinks stay hot for up to 12 hours and cold drinks for 24 hours. No more frequent refills: perfect for winter coffee, summer iced drinks, or post-workout hydration. Suitable for year-round use in various scenarios.

Each water bottle comes with a flip lid (for quick sipping without removing the lid) and a straw lid (for easy spill-free drinking). Equipped with a tight thread, it is 100% leak-proof even when tilted or shaken.
