A good water bottle is key for staying hydrated. A water bottle with a straw is even better, as it's more convenient to drink from and easier to use when you're on the go. This means you're more likely to drink more water, which is always a good thing. Most water bottles are not dishwasher safe, so if that's important to you, be sure to read the description carefully before making your purchase. When reviewing water bottles with straws for our roundup, we evaluated each pick for material, price, care instructions and functionality.
