S'well Insulated Bottle Stone Collection - Onyx

The S'well Insulated Bottle in Onyx from the S'well Stone Collection features an opaque, black finish and has a durable stone-like texture for added grip. Being made from 18/8 pro-grade stainless steel means your drink stays tasting like it should, and the triple-walled ThermaS'well™ technology keeps drinks cold for 24 hours, hot for 12 hours and the outside of the bottle dry. With a mouth designed to fit most ice cubes, this 500ml size fits comfortably into a standard-sized cupholder.
