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. In addition, S'well is a proud partner of UNICEF USA, helping provide clean and safe water to the world's most vulnerable communities, supporting water programs across Madagascar and educating families on water-borne diseases so that a sustainable, long lasting change is made around the world. S’well bottles are beautifully crafted, composed of non-leaching and non-toxic 18/8 stainless steel. All bottles are triple-walled, 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 different sizes.
