From S’well, the Onyx Bottle is a 500ml reusable Bottle from the Stone collection, designed with translucent, muted hues inspired by one of the most coveted semi-precious gems. Finished with a durable, stone-like texture for added grip, it brings a considered look to everyday hydration—whether you’re heading to the gym, commuting, or packing for holidays. Built with a triple-layered, vacuum-insulated design, it features Therma-S’well® Technology and high-grade 18/8 stainless steel to help keep drinks hot for up to 18 hours and cold for up to 36 hours. A condensation-free exterior means it won’t sweat in your hand or bag, while the wide mouth is designed to fit most ice cubes.
