And a fine foray it is. In addition to being an excellent insulated 24 oz water bottle, the Thermos uses its Smart Lid to offer a wealth of opportunities to keep track of your water intake and meet your hydration goals. 

The Smart Lid connects via Bluetooth to the Thermos Smart Lid app, which is compatible with most Apple devices. You can use it to set goals for yourself and track your hydration progress on a daily, weekly, and monthly basis.

7. CrazyCap 2.0 UV Water Bottle

The CrazyCap 2.0 UV Water Bottle is another entry into the UVC purifying smart bottle category. But this one stands apart from the pack because it’s been tested and certified by NSF International for Disinfection Performance.

The UV light is built right into the lid of the CrazyCap 2.0 UV Water Bottle, and it activates automatically to clean the bottle and its contents every four hours. It holds 17 oz and is a great option for travel and adventure.

The look of the CrazyCap 2.0 UV Water Bottle may not be for everyone, but that’s a minor issue in such a handy device. It has sort of a soda bottle-like shape and comes in a variety of colors. You can also get the CrazyCap lid on its own and match it up with the bottle of your choice.

8. TYLT All-In-One Water Bottle

I love it when somebody invents a thing that combines two objects that one would never think needed to go together. For example, take the TYLT All-In-One Water Bottle, which is an insulated water bottle with a built-in power bank. 

It sounds crazy, but what are the two things we pretty much all need to get through every day? Water, and a place to plug in our phones. The bottle holds 17 oz of water, and the battery has a charging capacity of 5,700 mAh, enough for two charges of your average smartphone.
