S'well started in 2010 with a 17oz hydration accessory, and has since grown into a suite of reusable products and accessories to fit your busy lifestyle, in a range of distinct prints and patterns to match your unique sense of style. Free of BPA & BPS in vacuum-insulated, high-grade 18/8 stainless steel, every S'well is beautifully designed to keep the things you love to eat and drink hotter or colder, longer than all the rest.
