When it comes to how much water you need to drink to stay properly hydrated, we’ve all heard the eight glasses a day mantra. But the truth is there is no one-size-fits-all number—daily water intake requirements vary from person to person and depend on factors like size, activity level, metabolism, climate, medications, and more.

While the recommended daily intake looks different from person to person, one thing we can all agree on is that hydrating daily is essential to our overall health. Investing in a reusable water bottle that fits your hydration needs and style is the logical next step. Just as a pair of new leggings can motivate you to get to the gym, a new water bottle is sure to update your hydration game.

What to Look for in a Water Bottle


The most popular water bottles are constructed from three primary materials—plastic, stainless steel, and glass. Plastic water bottles are usually affordable, lightweight, and portable. Most plastic water bottles on the market today are made from Tritan, a rock-hard plastic material that's BPA-, BPS-, and BPF-free. These hard plastic bottles look like glass yet are very difficult to break. Tritan is also dishwasher safe.

Stainless steel bottles offer insulation, keeping beverages at their respective temperatures for long periods of time. Bottles with double- and triple-walled insulation can even keep beverages hot or cold for upwards of 24 hours. This feature tends to make stainless steel bottles a bit heavier than plastic ones.

Glass bottles are less likely to alter the taste of your water or leave any residue. The downside is that glass is heavy and highly breakable. Many glass water bottles come in fashion-forward designs and are often sold at higher price points. 


Choosing the proper bottle size depends on your personal water intake needs, as well as your activity level. Also, it depends on your personal preference and whether you prefer to fill up in the morning and be done for the day or have a smaller bottle and refill throughout the day.


Water bottles come with varying styles of lids, with the most popular being screw-on, flip-top—often containing a straw-like spout—and sport nozzles. Lids offer convenience for different activities, which is why some athletes prefer a sports nozzle for a quick squirt of hydration during games.
