Swiss Tech Krug 64 oz Vacuum Insulated Stainless Steel Water Bottle Jug with Chug Cap and Silicone Boot Pet Bowl, Black

The 64-ounce capacity is huge and easily gets me through most of the day without needing a refill. The cap is easy to open with one hand and provides a smooth flow of water without leaking. One feature I didn't expect to use much is the silicone boot. It protects the bottom of the bottle from scratches and dents. Despite its large size, the built-in carry handle makes it comfortable to carry around. The bottle feels durable and well-made without being unnecessarily heavy.

Oh boy is this a great water jug!!! It is great for making sure I drink enough at work - I fill it up and try to finish the whole thing before I leave. My daughter rows, and the rubber boot is protective of the shell and keeps it from hitting too hard. The extra wide opening makes filling it with ice very easy - I can do it straight from the dispenser in my fridge. I haven't needed to keep anything cold for 48 hours, but I believe it would do well with that based off how cold my drink at work stayed.
