You're probably already well aware of how important it is to stay hydrated. But if you've had days when the clock strikes 5 and you've barely taken a sip of water, you likely also know how easy it is to forget.

Whether you're slipping it in your bag for running errands or placing it on your desk as you work, having a water bottle on hand can be a helpful reminder to drink more water. Not to mention, they're eco-friendly: If you have a sturdy water bottle, you won't be stuck having to buy a single-use, plastic one when you're in a pinch.

Thankfully, there are plenty of good options on the market. From bottles that track your water consumption to one that cleans itself, we found the best water bottles to help you reach your hydration goals.

Top-rated water bottles

Iron Flask Sports Water Bottle

This water bottle is the No. 1 bestseller on Amazon, and it's consistently well-reviewed — it has a 4.8-star average rating from more than 41,000 ratings. The stainless steel design keeps your water cool, and you can switch between the straw, flip or stainless steel lids, depending on how you like to drink your water. The best part? It comes in 19 fun colors, including multiple ombré options.

Fidus Large 1 Gallon Motivational Water

For those who are really trying to get serious about hydration, getting a water bottle that tracks your consumption can be super helpful. This one features fun sayings and goals to hit throughout the day. Since it's gallon-sized, you won't have to make constant trips to the fridge for refills.

Hidrate Spark Steel Smart Water Bottle

If the previous bottle feels too old school, this high-tech version will track your water intake and sync the data with a corresponding app on your phone. It'll tell you how close you are to hitting your daily goal, how many bottles it will take to get there and when you're on a water drinking streak.

LARQ Insulated Self-Cleaning and Stainless Steel Water Bottle

You're probably not washing out your water bottle enough, but thankfully this bottle does part of the work for you. It uses UV-C to kill bacteria in the bottle. While it still does require the occasional wash, one Shop TODAY writer said it's "worth it for some added peace of mind during the weeks when my lazy side takes over."
