Why customers choose Oico Home, Kitchen and Dining

Experience a refined blend of style and performance with the S'well 9oz Onyx Bottle. Constructed from 18/8 premium stainless steel, it features Therma-S'well Technology—a triple-layered, vacuum-insulated design that helps beverages stay colder for longer and hot for longer, all with a condensation-free exterior.

Designed for everyday moments, this compact bottle fits easily in cup holders and bags, making it a reliable companion for commutes, workouts, and weekend adventures. The opening is wide enough for most ice cubes, so you can refill and refresh with ease while maintaining your preferred beverage temperature.

Key benefits at a glance

  • Triple-layer insulation with vacuum seals keeps drinks cold up to 24 hours and hot up to 12 hours.
  • Condensation-free exterior makes it comfortable to hold and prevents moisture in your bag.
  • Made from 18/8 food-grade stainless steel, BPA/BPS-free, and built to last.
  • California Prop 65 compliance noted; a sustainable alternative to disposable bottles.

Beyond performance, the Onyx bottle is a design statement—sleek, durable, and easy to clean by hand. Each colorway is crafted to complement a busy lifestyle and a growing commitment to reduce single-use plastics. The bottle is intended for repeated use and long-term enjoyment, inviting you to hydrate with confidence whether you’re chasing a sunrise run or a late-day project.

Practical tips for use and care:

  • Rinse and hand-wash to maintain the exterior finish and insulation efficiency.
  • Keep beverages within your preferred temperature for extended periods as you move through your day.
  • Pair with other S'well pieces for a coordinated hydration routine that travels well.
