Brand story

We've sold a lot of water bottles at Biome for 18 years, and EcoVessel takes the prize for the best quality!

  • The lids are solid and sturdy - and replaceable if ever needed.
  • We love the silicone base cap that protects the bottle when dropped.
  • Wide mouth for easy cleaning and filling.

Best of all, the Triple Insulation properties are phenomenal. Tracey's cousin lives in the outback and their children take insulated EcoVessel to school with ice and they come home with ice still in the bottle.

A family business based in Boulder Colorado EcoVessel seeks to provide solutions to replace wasteful single use bottles. EcoVessel BPA free stainless steel insulated bottles all come with lifetime warranties so you can be sure they'll go the distance.

    Fabulous water bottle

    This water bottle really delivers as it says. Ice remains the next day even after the bottle has been sitting in the sun in 34c heat. I ride a motorcycle and wanted a bottle that would keep my drinks icy cold even on the hottest days sitting in a black top box in full sun for hours on end.
