Reusable water bottles are a must-have for summer no matter where you live. They are also made in all sorts of super cute designs, colors, and styles.

My favorite is Camelbak, which you can find just about anywhere. I love the bite valve and that you can get different sizes to fit in your car, gym bag, or purse! The following water bottles are all from Target.

This is the exact one that I have. When I'm at work, I try to drink 2 of these in a 12-hour shift.

$13.99 from Target.

This one is indented on the bottom so that it will fit in most standard car cupholders.

$11.99 from Target.

The double-insulated Camelbak ensures that your water stays ice cold.

$19.99 form Target.

Because I am still a kid at heart, I also have this one, which is about half the size of the standard Camelbak but has fairies on the outside and a lime green valve/straw. It fits perfectly in my purse for those days when you aren't necessarily going to the gym, but still want to stay hydrated.

$12.99 from Target.
