Earthlust water bottles make it fun to hydrate on-the-go. They're made from food-grade stainless steel, which is naturally safe unlined (so you don't have to worry about ingesting pesky BPAs). They're easy to carry, with a loop in the cap so it can swing from your finger, and also with a carabiner that attaches to a pack or beltloop. While you're swooning over the fab designs, you'll be happy to know that they use non-toxic paints and that the caps are BPA-free polypropylene #5 and recyclable. Have fun!
