The ChicoBag Bottle Sling carries a single water bottle crossbody on an adjustable strap, with a zippered front pocket sized for a phone and keys — enough carrying capacity to leave the daypack at home for a short hike or errand. It’s made from recycled-PET fabric with a recycled-aluminum carabiner, and the whole sling stuffs into its own built-in pouch about the size of a fist when not in use.
