Ninja Thirsti 24oz. Travel Water Bottle, Stainless Steel Tumbler for Carbonated Drinks, Purple

This is a great size as many water bottles are either too small or massive in size. It fits in my car cup holder. Keeps the drink cold and fizzy as advertised (keep it full when storing a long time because if it is mostly empty your mileage may vary). I actually use it to hold drinks made by a different carbonation device but I like the handle and the attached lid. The lid locks out straight so it does not get in the way when you drink out of the spout. I bought the bottle that was available but it is a nice color that seems true to the picture to my eyes. For people that like to extend the life of their bottle hand washing is easy due to the wide mouth.
