The patent pending push button flip straw lid design allows for easy sipping and eliminates spills, making it a great option for outdoor activities, traveling, and everyday use. The vacuum insulation technology keeps your drinks cold for up to 24 hours, ensuring that you stay refreshed and hydrated all day long. TOP INSULATION TECHNOLOGY: The Hydraflow Capri stainless steel tumbler cup features top of the line triple wall vacuum insulation with premium copper lining for maximum insulation of warm or cold beverages. I have also found that the lid isn’t leakproof as liquid leaks from the ‘gulp’ opening (I have since noticed that the 40oz version has a slightly different lid, which seems to close more securely) but I’ve equally found that this isn’t much of an issue unless the cup is tipped on its side and even when aggressively shaking the cup, only a small amount of liquid comes out of this opening. The lid doesn’t screw on and easily pops on and off but there is a rubber seal around the lid which makes this feel more secure. HIGH-QUALITY MATERIALS: Our reusable cups are BPA-free, made with premium 18/8 stainless steel material for enhanced durability while minimizing metallic taste. They also feature a dual lid for direct sipping or use with our included metal straw.

The wide mouth design makes it easy to fill and clean, and the stylish design and carry handle add a touch of elegance to your hydration routine. This eco-friendly and sustainable bottle reduces the need for disposable plastic bottles and helps to reduce waste in the environment. Introducing the Hybrid Bottle with Flip Straw Lid - the ultimate solution for on-the-go hydration! This bottle comes in three sizes, 17 oz, 25 oz, and 34 oz, and is made from a combination of high-quality 304 stainless steel and BPA-free plastics, and features a copper lining for extra insulation to keep your beverages at the perfect temperature. KEEP LIQUIDS ICY COLD OR STEAMING HOT: The sleek triple wall design keeps drinks cold for up to 12 hours and hot for up to 6 hours while preventing condensation and moisture from collecting on your tumbler.
