This 64 oz Gatorade jug is huge and perfect for sports or trips. It's very solid and has a rubber grip on the backside of the jug which is great if your hands are wet or sweaty. The lid twists off and on and has a flip lid. I have only used this for cold liquids but it seems to keep things cold for a reasonable amount of time. Inside the jug it has a piercer insert for gatorade pods, but it easily removes if you don't need to use it. Another nice feature is the fence hook on the handle, as well as the label to write you or your kids name on. So far I have had no major issues with the jug, but I have noticed that the fliplid doesn't always stay closed, so be careful if just tossing this into a bag. Overall, we love the size and the durability and it's been getting tons of use.
