S'well is the only reusable bottle that looks great and does good. It keeps your drinks cold for 24 hours and hot for 12, while giving back to those in need. S'well bottles are beautifully crafted composed of non-leaching and non-toxic 18/8 stainless steel. The bottles are triple-walled, containing a layer of copper between the internal walls, leaving no condensation on the exterior. Whether you need a bottle small enough to fit in your purse, or big enough for a picnic, S'well fits all purposes and comes in three sizes: 9oz, 17oz and 25oz. Take your morning coffee or tea to go in a 9oz bottle, or fill it with juice for your little one's lunchbox. The17oz will keep just the right amount of water ice cold through a hot yoga class or long board meeting. Fill up a 25oz with an entire bottle of wine so you can cheers wherever a night may take you.
