The Croco Metal Bottle is made of 18/8 steel and its leakproof pop-up straw makes it ideal for grabbing for a quick chug on the go, plus the carry loop attaches easily to a bag, backpack, or buggy. With no coatings on the inside of the bottle, it won't release any kind of flavor or chemicals and we love the fact that it comes with a backup straw. Colour: Green Croco (Green).
