Isothermal bottles offer many advantages:

  • Thermal insulation: Keep your drinks hot for up to 12 hours and cold for up to 24 hours.
  • Ecological: Reduce your use of disposable plastic bottles.
  • Economical: Investing in an insulated water bottle saves you money on bottled water, for example.
  • Practical: Take your favorite beverages with you wherever you go, whether at the office, the gym or in the great outdoors.

In our online store, you'll find stainless steel isothermal water bottles in 1-liter or 500ml sizes. A 1L isothermal water bottle lets you carry a large quantity of hot or iced tea, infusion or coffee, or simply water to stay hydrated without having to refill it constantly.

An essential accessory for tea lovers and specially designed for Qwetch water bottles, our infuser stopper infuses the leaves directly into the bottle. Ingenious and practical!
