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.

Sick of your large Eco Vessel bottle going flying every time you turn a corner? Check out Willy and Bear for a creative solution that will keep your bottle secure in the car.

    Really stays icy.

    I wanted a water bottle that would keep ice overnight when I do overnight rides on my motorbike. Sitting in my black top box in 34c heat the water bottle still had ice the next morning. Very happy with my purchase.

    Thinner bottle great for the car and school bag pockets

    Works great except for the silicone bumper, which keeps coming off.
