Perfect for your child's water bottle to take to school! Whether you've broken your water bottle cover and need a new one, want a shoulder-strap water bottle cover, or are finding it inconvenient to buy a cover for each size water bottle, this water bottle cover was created in response to feedback from a childcare worker mom, pursuing versatility and durability. We partner with a specialized water bottle manufacturer that has selected over 20 water bottle holder manufacturers to evaluate both quality and functionality. From numerous samples, we selected polypropylene for its versatility and durability. We have also received complaints that the belt on the bottom tends to lean to one side, causing the water bottle to fall, so we have improved the bottom of our product by making it cross-shaped to prevent it from falling.
