ecotanka thermoTANKA – Pure stainless steel. Premium performance.
Discover the ecotanka thermoTANKA series—where precision engineering meets sustainable innovation. Proudly established in New Zealand in 2005, ecotanka pioneered the original 800ml double-wall vacuum stainless steel bottle (originally known as the PolarTanka), setting a new standard long before imitations followed.

Spanning sizes from 350ml to 2000ml, the thermoTANKA range is crafted from high-quality 18/8 304 food-grade stainless steel for unmatched durability, safety, and sleek design.

At the core of every thermoTANKA is our advanced vacuum insulation technology, designed to keep drinks cold for up to 24 hours or hot for up to 12 hours. The wide-mouth opening makes adding ice cubes easy, while priming the bottle with boiling water for 5 minutes before use enhances heat retention for hot beverages.

More than just a bottle, the thermoTANKA series reflects a commitment to sustainable living. By choosing reusable, fully recyclable stainless steel, you’re helping reduce plastic waste and protect the planet—one refill at a time.

1200ml thermoTANKA – Built for big days and serious hydration.
The ecotanka 1200ml thermoTANKA is designed for those who need more from their bottle—more capacity, more durability, and more reliability. Whether you’re heading off on a long hike, powering through a demanding workday, or just need to drink more water, this double-wall vacuum bottle has you covered.

Crafted from high-quality 18/8 stainless steel, it's a rugged and reusable alternative to single-use plastics—ready to handle whatever your day throws at it.

ScrewTop Lid
The ecotanka ScrewTop lid is thoughtfully designed to have a big opening for fitting onto the bottle, while another small top cap makes it easier for drinking on the go. The small top cap has a unique feature, being interchangeable with most soda bottle lids on the market. The ScrewTop lid ensures a secure, leak-proof seal, offering peace of mind knowing your beverage will stay contained, regardless of your activities.
