I love this Cool Bands Triatan Water bottle! This is a gorgeous design, and a fun concept. The arm bands are fun to take off and wear and when I am done I can put them right back on the bottle for safe keeping! The water bottle is 24 ounces and it great for taking with me on hikes or trips in the car or for just when I am at work! You have a variety of colors to choose from with different sayings. I love the Music on World off one for me! I also love that it is shatterproof, considering I drop them all the time!
