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.

350ml thermoTANKA – Compact, powerful, and perfectly portable.
The ecotanka 350ml thermoTANKA is the smallest in our double-wall vacuum range—designed for short outings, school bags, travel, or worksite smoko breaks. Despite its compact size, this bottle delivers powerful thermal performance.

Stylish, reusable, and endlessly practical—the 350ml thermoTANKA is your everyday hydration companion in a compact size.

Bamboo & Stainless Steel Lid
The ecotanka Bamboo Stainless Steel Lid brings a natural, stylish touch to your drink bottle. Crafted for durability and sustainability, it features food-grade stainless steel paired with a smooth, natural bamboo top. A secure silicone seal keeps your bottle leak-proof, while the built-in carry handle makes it ideal for life on the move. Whether as an upgrade or replacement, it's the perfect blend of function and eco-friendly design.

Minimalist in design, timeless in appeal, and suitable for all ages, the thermoTANKA is your stylish, eco-friendly hydration partner for any adventure.
