Our Verdict

Soma is a relatively new company that produces trendy water filtration systems, beakers, and carafes. They just started making water bottles and the Soma water bottle was our second glass option, tested next to the Lifefactory Glass Flip Cap. The Soma bottle is smaller, holding 17 oz of liquid. It also has a silicone sleeve and a bamboo lid, making it the ultimate eco-health-friendly bottle. We loved all of these features, but the Soma's sleek design made it difficult to stand up on its own on a table; it was constantly falling over. It did do well in our taste tests, like the Lifefactory, and retained hardly any flavor from the sports drinks or soap.

Editors' Choice Award
Though it is heavier than other bottles in our review, it takes the cake for versatility, sleek design, and insulating properties, making it the Editors' Choice of the year.
Best Buy Award
A tried and tested classic, the Wide Mouth bottle wins again as our Top Pick for Plastic, as well as the Best Bang for your Buck bottle.
A take on the Classic version, it's simple, sleek, and will keep your drinks hot or cold.
We were pleasantly surprised by the Brazos unique autoseal button for easy one-handed drinking; this insulated bottle works great for hot or cold beverages.
The Classic sport cap is an updated version of our longtime favorite, the Klean Kanteen Classic. Whichever lid you choose, the Classic is a durable, light stainless bottle that we love.
Top Pick Award
The Flip Cap is an updated version of the Classic, with all the same features we loved, plus a new cap design.
The Soma Bottle is a new product from a company that produces glass beakers and water filters. It looks cool and is made of bamboo, glass, and silicone.
The CamelBak Chute is the largest vacuum insulated bottle we tested, with a lid that allows you to fill with a wide mouth, but drink out of a smaller spout.
Top Pick Award
With its unmatched lightweight design and packability, this contender is our Top Pick for Collapsible Bottles.
This contender is a light, plastic bottle; it's light enough to use for hiking, but also portable and small enough to use around town.
The Citrus Zinger is a bottle designed specifically for those who enjoy citrus infused water, with a straw for one handed drinking.
The Thermalock Glacier is a insulated bottle designed specifically for keeping drinks cold, and thus has a wide mouth to make filling with ice easier.
The Nomader bottle attempts to solve the problem of being both collapsible and easy to drink from, but falls short on its ability to collapse effectively.

The Soma Water Bottle is a sleek little bottle that in its design had more focus on fashion than function. It is small and slender, making it a good bottle to accompany you to work.

Performance Comparison

Ease of Use

The narrow mouth of the Soma makes it hard to fill up but easy to drink from. The lid is bamboo with plastic on the inside and it fits well on the top of the bottle with only one full rotation to tighten. One problem we ran into when filling the bottle was its tendency to overflow due to its small size. When filling from a fast spout or a portable water jug, the bottle would fill with water too quickly, not allowing us time to turn the water off before overflowing all over our hands and arms. Not a deal breaker, but something to note when filling in non-traditional settings (i.e. somewhere besides the sink).

The Klean Kanteen Vacuum Insulated also struggled in this catagory due to its narrow mouth. The other issue with the Soma was the fact that it seemed to be perpetually falling over. The narrow base, with a slight upturned curve, makes the bottle act like a bowling pin minus the flat part on the bottom, even on completely flat surfaces. This tipping tendency was the main issue with the bottle and the reason it received low scores in the ease-of-use category. The LifeFactory Glass Flip Cap proved to be a much more stable glass bottle and is our suggestion for an around-town bottle.

The Soma Bottle's sleek size makes it a good bottle to accompany you throughout your day-from work to the climbing gym.

Perhaps to make up for its tendency to tip over, the Soma is well suited for falling; it is incredibly durable despite its delicate appearance. The silicone sleeve protected the glass well when the bottle was dropped onto hard surfaces. The lid, however, showed a few signs of weakness. It may have been user error, but a small gasket slipped out of the inside of the lid the first day we used the bottle and we were unable to get it back in. The bottle did not seem to leak more after, but a part of the lid did come off almost immediately. Out of the two glass bottles, the LifeFactory Glass Flip Cap scored higher in durability because it stands up better and has a more substantial lid design. Metal or plastic bottles tend to be more durable, and some of the top picks for a similar holding volume to the Soma are the Avex Brazos Autoseal Stainless or the CamelBak Eddy.

The narrow mouth (only an inch in diameter)  makes the Soma difficult to clean. Some prefer this small mouth for drinking because it reduces spillage.

Ease of Cleaning

The mouth of the bottle is very narrow, making cleaning the inside difficult. The Soma compares to the Platypus Softbottle in degree of difficulty to clean the inside. In this category, the Lifefactory fared better due to its wider mouth. Another issue that popped up after a few months of use with the Soma bottle was the accumulation of water between the silicone sleeve and the glass. This became an issue when we noticed mold beginning to grow in this area, and it is difficult to remove the sleeve to clean the inside of the sleeve. The LifeFactory's sleeve has many more holes, and thus allows for more air to get between the sleeve and the bottle. This bottle did not accumulate mold between the sleeve and bottle.


At only 10 oz, which is light for a glass bottle, weight is where the Soma bottle really shines. That said, it is not a very large bottle, so its weight reflects its size directly. The bamboo lid contributes to the slimmed down, lightweight design. The lightest bottle in our review was the Platypus Softbottle, weighing in at 1.2 oz. The Camelbak Eddy weighed 6 oz, while the Nalgene Wide-mouth weighed 6.25 oz.


Time and time again glass bottles prove their superiority in terms of their ability to shed lingering tastes. The Soma is no exception, and stood up to the Lifefactory in its ability to keep water tasting, well, like water! Similar contenders were the Hydro Flask Wide-Mouth, our Editors' Choice winner, LifeFactory Glass Flip, and the Soma Water Bottle.

The glass construction and bamboo/plastic lid held up to the taste tests by not retaining flavors  even after switching between drinks.

Best Application

Since it has such a small carrying capacity, the Soma bottle is a good option around town. At work, thrown in the bottom of your workout bag, or used at home instead of a glass, the Soma does well…providing it is close to a place it can be refilled. Another bottle that works well in this capacity is the collapsible Nomader Collapsible, which has a similar carrying capacity. The Soma takes the cake though, with it is stylish looking so you might get compliments at your local trendy coffee shop.


Because the company is new and focused on making products of a high quality, the Soma bottle is a bit expensive for the size and range of versatility it provides. At $30, you are making an investment in the Soma company values, where they give a portion of every purchase to water-related non-profits and other projects. In general, glass bottles will be more expensive than other bottles — the Lifefactory Glass Flip Cap comes in at $25, compared to the plastic Nalgene Wide-Mouth or CamelBak Eddy, which are $11 or $15 respectively.


The Soma Bottle is stylish and sleek, but comes up short as to functionality. It's a good bottle to accompany you around town, but will not fare on an outing much more involved than that. It is also very tippy and struggles to stand up on its own without falling over — another feature that decreases the bottle's ease-of-use.
