Such a clever idea! No longer do you have to worry about your keys, ID, money, etc., when you go to the gym.  Just take this water bottle and stick your stuff in the hidden compartment! When you want to shop at a flea market, or craft fair, you don’t have to worry about lugging that big purse around.  You always need water on those outings, right? So just take your credit card, ID, key, and fill up this large water bottle and you are good to go!  You just press to sip and release to seal (100% leak proof), so it’s really hands-free.  Has a clip so you can attach to your stroller or bag strap.  Lots of colors to choose from, and even smaller sizes for the kiddos!
