Our Verdict

As one of our longstanding favorites, we have bought and tested multiple iterations of the Lifefactory Glass Flip Cap. This version has a different flip cap to top the classic 22oz bottle. Though we still like the Lifefactory as much as always, the cap design wasn't trustworthy inside our pack, and it leaked a few times inside our bags. We still love the ergonomic shape of the bottle and the comfortable carrying handle. The Lifefactory still has a place on our desk, even if it falls short of being our favorite. We liked to think of this one as a portable glass, rather than a water bottle and found it best suited for urban use.

Our Analysis and Test Results

The Lifefactory had a few issues that lowered its ease of use scores, but it held its own in terms of ease of cleaning, taste, and durability.

Ease of Use


The updated 22-ounce Lifefactory has the same sleek shape as the previous model, with an updated lid that changed its score in this metric. The new lid has an ergonomically shaped spout with its own cap, complete with a silicone insert to keep it sealed. Though we preferred this spout system over the previous version, we still had a hard time trusting the cap when the bottle was loose in our backpacks. A subtle click of a tiny plastic tab is all that keeps the contents of the bottle inside, and this made us nervous. More than once, this bottle leaked in our bag, greatly reducing its score in this metric. Despite our hold-ups with the spout, we did like the hinged carrying handle, which is large enough for a few fingers, but stows on the side when not in use. We found that we actually used it frequently, unlike other bottles with smaller carrying handles.

We found that cleaning this one is actually quite easy — as the bottle's mouth is wide enough to easily fit a brush inside. The lid is complex but easy enough to clean if you really need to get in there. The removable silicone insert in the flip cap also facilitates cleaning.

Durability


Once again, the silicone sleeve does its job. We were impressed by the Lifefactory and its ability to withstand everything we put it through during our test period. We left this bottle on the floor of the gym, used it at coffee shops, and drank out of it in campgrounds. We treated this bottle as we would any other, and it survived. The silicone sleeve protects the glass bottle inside, with rubber reinforcement on the bottom of the bottle.

The lid held up during our test period, but the fact that it has two hinged components makes us a bit nervous. The flip cap lid already tends to leak, which means that any additional wear could render the bottle useless. We recommend taking good care with this feature.

Weight


The thick, durable glass, the intricate lid, and the silicone sleeve all add up to make a fairly hefty bottle. Weight is not the strong suit of the Lifefactory bottle; and with a total weight of 18.6 ounces, it is one of the heavier bottles in our review. When full, this bottle weighs over two pounds, which isn't out of the question to add to a backpack or messenger bag to and from work. Since the bottle is glass and has a small capacity, we wouldn't advise taking this one out into the backcountry on the weekends, though.

Taste


As you might expect from a glass bottle, the Lifefactory scored at the top of the pack in this metric. Its scores were comparable to the other glass bottles in this review. We found that it scored lower than the other glass bottles in this review because of the plastic spout. The other glass options we tested have simple screw caps, where you drink straight from the glass, rather than through a plastic spout. This spout did impart a little bit of flavor from our sports drink mix used for testing in this metric.

The spout is a bit of a trap for flavors, but the silicone sleeve is...

Value


The Lifefactory Flip Cap is a reasonable purchase for your go-to everyday bottle. While there are now more affordable options out there for glass bottles, the Lifefactory bottle is a tried and true option. The flip cap is an added feature that facilitates drinking on the go, making this one slightly more expensive.

Conclusion


The reign of the Lifefactory Glass Flip Cap as our Top Pick ended with the advent of the newly designed flip cap. This lid, though durable and easy to drink from, added complexity to the bottle that resulted in some leakage. It's hard to trust this bottle won't leak inside our packs. We still liked the bottle for its shape, ease of cleaning, and durability, but have found that there is a myriad of other options out there that are more affordable and work just as well.
