Heading out on a hike this weekend? Or perhaps catching a music festival coming to town? If you’ve got plans coming up that will keep you outdoors for an extended amount of time, remember to keep yourself hydrated throughout the day so you can keep the summer fun going.

Even if you tend not to be much of a water drinker and instead prefer a flavored drink, then water bottle add-ins make a great alternative in helping to keep you replenished. They’re also convenient and easy to take along with you, plus won’t weigh you down with sugar like many sodas and other sweetened drinks can.
