    Overall, the bottle is great! I love the three-color customization as well as the quality, durability, and flexibility of the shape (fits great in hand or cup holder). Only two real issues. The half-twist cap is more like 1/4-3/4 twist, as there isn’t a opening IN the cap, it’s just a matter of loosening it to the right amount. It doesn’t shut consistently or otherwise line up in any way. The other more serious letdown is the insulation. Ice water stays icy for less than an hour, and the water is room temperature no more than two hours after that. Considering the stainless model is rated for 24 hours cold, I expected a lot better than 3-4 with the Lifestyle version.

      Customer Service

      Hello Andrew,
      We really appreciate you taking the time to share your experience with your Ergo bottle.
      Just to clarify, the droplet is just a guideline. The cap will actually open and allow the flow of water in several places along the turn. It does not have to be a half twist opening it’s just a guide to line up with the droplet to work. It’s possible that when the cap was produced, the droplet wasn’t lined up correctly on the cap. Our bottles go through several levels of quality control before they are shipped out but sometimes faulty products fall through the cracks. Because of this, we offer a lifetime guarantee on all our products and we would be happy to replace the cap. Please just shoot us an email ( We find that the Ergo bottle works best when packed full of ice and water. The colder the water is initially, the longer it will stay cold. Hope this helps!
      Looking forward to hearing from you.

    These water bottles are the best! Our two youngest use these for long haul bike rides (20 miles +), Tae Kwon Do, and their nightstands. In other words, everything! They love the colors they picked and they don’t leak! Great bottles!!!–

Frequently Asked Questions

The Polar Bottle Ergo is manufactured in our Boulder, CO headquarters with parts sourced from Denver, CO and Garden City, MO.

Polar Bottle products are made from LDPE, HDPE, and Tritan™ plastics, which are free of harmful chemicals like BPA and Phthalates. To the furthest extent of current scientific knowledge, none of these plastics contain harmful chemicals that may leach into the liquid contained in the bottle. The well-being of our customers is of the highest priority to our company and plastic safety is an issue we take very seriously.

Polar Bottle water bottles have always been BPA and Phthalate Free.

Ergo is fitted with our sip-through Half-Twist® cap. The half twist design allows you to drink directly from the lid, preventing spills and making it simple to use on the go. The design also delivers the ideal flow of water — a truly perfect sip with each drink.

To use the cap, simply line up the water droplets on the bottle and cap to start the flow of water. To close, twist the cap all the way in the other direction until it is completely sealed. A medical-grade silicone gasket inside the cap prevents spilling and leaking.

The Polar Bottle Ergo is dishwasher safe. The gasket inside the cap is also removable for easy cleaning. Ergo is not freezer safe.

Thanks to it’s hard plastic materials, Polar Bottle Ergo works for both hot & cold liquids. The bottle’s dual-wall design maintains temperature twice as long as standard single-wall, uninsulated bottle.

Polar Bottle Ergo will fit easily into most cup holders. However, it is not designed as a cycling product and will not fit in most bike cages.
