Now it's easier than ever to take your water bottle with you on the go! This water bottle collapses down to a compact size when not in use, so just tuck it into your backpack or suitcase, or attach it to your bag with the handy carabiner clip. When you're ready to fill it, just pull gently to expand it into a regular-size bottle. It's the new essential you won't want to travel without. It's also perfect for school, the beach, or the gym.
