Polar Bottle Ergo Review

One of many USA-made insulated plastic water bottles offered by Polar Bottle, the Ergo is a neat 22-ounce bottle which provides a bit more of an ergonomic design compared to its older relative the classic “Sport” Polar Bottle. But just like the Sport models, the Ergo features the insulated design and durable construction which has made Polar Bottle popular.

Polar Bottle was kind enough to send us a sample for review, so I had a chance to get up close and personal with my very own 22-ounce Ergo Polar Bottle, and heres what I found.

Getting to Know the Polar Bottle Ergo

The Polar Bottle Ergo arrived with no additional packaging except for the plain brown box it came in. This is fine, since I don’t think there is much you could really do to hurt the Ergo. Short of burning it, piercing it with something sharp, running it over, or something equally catastrophic, I doubt many people will manage to put an Ergo out of commission. The bottle is made from an extremely durable and somewhat flexible plastic. 100% BPA and phthalate free, it is completely safe to drink from and as far as I can tell doesn’t leech any flavor into the water.Polar Bottle Ergo Water Bottle Demonstrating Vacuum Insulation Squish

My Polar Bottle has a decent look to it, but I have to admit I don’t find it as snazzy in person as I did in product photos. As you can clearly see in various images like the Amazon photo to the right, the Polar Bottle Ergo has something of an odd look due to the fact that there are two layers of plastic and the inner layer is sort of “squished” in various ways. I assume this is due to the vacuum insulation between the two layers causing the inner plastic to deform a bit – but that is really just a guess!

This lends a unique look to the Polar Bottle, but I’m not entirely sure it will be to everyone’s liking. However, as you can see for yourself in the pictures, my Ergo actually looks pretty snazzy at a distance and its only when you get up-close and personal that you can notice the somewhat unusual appearance.

A Look Inside

My first question when I got my Ergo was just how well the insulation works. I was eager to test it, so I quickly opened it up and washed it. As I was washing it out, I noticed the inside of the bottle has little dimples all over its inner walls (pictured below) – presumably to increase surface area and allow the bottle to hold more liquid! A clever little addition.

The next thing to catch my attention was the lid, which features a rather intricate plastic gasket designed to make the Polar Bottle leak proof – which it is. This gasket (pictured right) is made from medical grade silicon and is the crowning feature of Polar Bottle’s “Half-Twist™” technology, which makes the lid easy to open with a small motion yet still able to seal adequately to prevent leaks.

The Half-Twist does its job quite well – even when completely full, I don’t get any leakage from my Polar Bottle despite inverting it needlessly, tossing it about, shaking it, and generally trying to coax it to leak.


So About That Insulation?

After playing with the Ergo for a bit, I filled it up with ice and water and set it outside in the direct sun to put the insulation to the test. I left it outside unattended for about 4 hours – 3 of which were in direct sunlight. When I came back, my ice had melted entirely, yet the water was still quite cold as if it had been in a freezer.

Overall, I found this pretty impressive. Its definitely not the kind of amazing insulation top-of-the-line double-walled stainless steel water bottles offer, but then its important to keep in mind that this Polar Bottle is about a third of the price of those and yet is performing quite admirably – those hours in the sun sitting on concrete were harsher conditions than I’d want to store my drinking water in most of the time! Yet when I took a sip after the ice had melted, it was still pure, cold, and supremely refreshing.

 Review Summary

Appearance: 6/10

Ultimately we don’t think the Ergo is much of a looker, but its far from unattractive.

Functionality: 8/10Polar Bottle Ergo on its side

The Ergo gets high marks for functionality thanks to its innovative Half-Twist Lid with leak proof gasket, and insulated design. We also quite enjoy the wide mouth opening which makes it easy to refill and add normal sized ice cubes. The mouth is wide enough to allow for some cleaning, but since the 22 ounce capacity makes the bottle rather deep, a bottle brush maybe required to clean the deepest parts of the Ergo.

Durability: 10/10

In your day to day life, the kind of trauma your water bottle might suffer are generally fairly limited. Barring some freak accident, the Polar Bottle Ergo is going to keep on trucking. Super durable plastics make this water bottle impervious to most abuse.

Cost: 9/10

For about $12 on Amazon, the Ergo offers an impressive 22-ounce capacity, super convenient leak proof lid, an intensely durable construction and the quality insulation which has given Polar Bottle its name in the business.

Overall Rating: 4.7/5

We give the Polar Bottle Ergo a Very Good rating of 4.7/5.  It would is a fantastic everyday water bottle well suited to the challenges of regular, constant usage and available at a bargain price.
