We know a fundamental key to good health is drinking plenty of water. And as the weather heats up, the need to stay hydrated becomes even more important. If you're looking to up your water intake, you could use an app or make a plan to chug a glass after each bathroom break and before each meal. But an easier way would simply be to upgrade your water bottle. We've found it's a surefire way to keep you engaged and drinking more. And depending on what you're looking for—stylish customization, a built-in filter, naturally-imparted minerals—there's a bottle for you. We had the Valet. team round up some of our favorites. A few we've been using since the pandemic started, others are currently on our wish lists for our own personal upgrades.
