Review on 🚰 Sfee Insulated Water Bottle, 17oz Stainless Steel Reusable Bottle - Leak Proof BPA-Free Sports Cup for Hot and Cold Drinks - Ideal for Running, Gym, Workout, Cycling, Kids by Gent Dobson

If you like the water nice and cold, this is what you need. As a result, I drank a lot more water than before. Now I usually have one of these with ice water at home, at work, and in my car. I even started taking it with me on trips after noticing other travelers had it; Just make sure it's empty when you go through airport security and that's not a problem. I fill it with cold water bought at the terminal and I really like the coolness in flight and throughout the journey. The water stays cold for about 4-6 hours; left overnight, in the morning there is no frost. You can put it in the fridge overnight and it will eventually get cold.
