The AVEX Autoseal Technology Lid.
Eye-catching colors, high-end textures and materials, innovative functionality and health-minded design all recommend AVEX bottles for the discerning buyer.

From Left to Right: 25 oz. BPA-free Plastic Brazos with Autoseal Technology; 20 oz. Glass Clarity; 24 oz. Stainless Steel Brazos with Autoseal Technology.
I’ve been testing three models of AVEX water bottles and have been impressed with their high-tech features and unique style.
AVEX Bottle Design & Materials
The AVEX bottle lineup’s aesthetics deserve commendation. The colors, materials and shapes of the models I’ve been using are fun and rich. Whether in the back woods or front office, these bottles stand out for their style
The 24 oz. Brazos, which is sculpted of stainless steel and finished in a matte midnight blue, makes a strong first impression.

The 24 oz. Brazos AVEX Bottle is a masterwork of un-stuffy and masculine industrial design.
The sophisticated masculinity of the material begs to be touched. I found myself reaching for this bottle’s satiny finish even when not thirsty. Think of a mint-condition DeLorean powder coated in cobalt and you start to understand the bottle’s appeal.
Cool to the touch and easy to grasp, it’s difficult to not love the look and feel of the stainless steel Brazos.
The Brazos design also comes in BPA-free plastic. The 25 oz. Brazos in transparent blue lacks some of the luxury of its steel cousin, but the plastic offers the benefit of being top-rack dishwasher safe. If forgiving a bit of posh for practicality is in order, plastic wins the day.
The transparent blue of the plastic Brazos shows off the bottle’s handsome and understated lines. The cylindrical body eases in at a high waist for simple gripping.
Both the stainless and plastic Brazos bottles feature an innovative plastic lid. More on the tech later. For now, it’s worth noting that the lids are formed of a mix of soft and rubberized plastics. They feel durable while maintaining the high-end aesthetics of the bodies.

The Autoseal Technology integrated into the Brazos lids is only part of the cap story. The materials and colors on the lids add to the bottles’ aesthetics.
The lids feature colors that complement the bottles’ body colors. The color combinations suggest a bit of dot-com spunk. Neon green with three shades of gray and some collegiate blue are found on one cap. The other has a healthy share of bright orange. The color combinations work well and add some flourish to the finish.
The 20 oz. Clarity glass bottle I’ve been using is wrapped in an electric green non-slip silicone sleeve. The sleeve is fantastic for both flair and grip. Should that grip fail, it also offers some padding so the bottle (hopefully) won’t break easily.

The AVEX Clarity Glass Bottle.
The glass itself is thick and sturdy feeling, even rugged. And it offers respite from any chemical risks associated with plastics. The Clarity provides a completely plastic-free drinking experience. Plus it’s top-rack dishwasher safe, so it also offers a completely hassle-free experience.

The Clarity Glass Bottle features a clever silicone sleeve and canteen-inspired cap design.
The canteen-style aluminum cap that twists on at the top adds to the Clarity’s durable feel and ready-for-the-outdoors looks. A holding strap with a rubberized grip is affixed to the bottle’s neck with a metal clamp. The overall styling effect of the Clarity is very much smartphone-era canteen.

The integrated strap allows for the bottle to be tied, looped or clipped to packs, branches or just about anything else.
AVEX Bottle Function
The real technological story of the AVEX bottle lineup is in what AVEX calls its Autoseal Technology. Both Brazos models I tested came equipped with Autoseal lids.

The AVEX Bottle Autoseal Technology: Press to drink.
The Autoseal caps enable single-handed gulping without leaks. Simply press the integrated button, tilt the bottle bottoms-up and enjoy. When finished quaffing, release the button.

The AVEX Bottle Autoseal Technology: Release to seal.
The button connects with an internal spring-loaded system that opens a sip-sized spout. The spout can be covered when not in use by a flip top dust shield. And the shield can be rotated and stowed in a built-in nook in the cap body.

The AVEX Bottle Autoseal Technology includes an integrated dust shield to cover the spout.
Topping things off is a handle for attaching the bottle to a strap or carabineer.
The Autoseal Technology works as intended, and it’s more fun to use than it ought to be. There’s gratification in pressing that button. Plus, the Autoseal caps look like they’re straight out of a Transformers movie with all the interconnecting pieces and hidden mechanisms. Very cool.

The inner workings of the AVEX Bottle Autoseal Technology.
Speaking of cool, the bottles all performed well in keeping liquids frosty. Most adept at the task is the stainless steel Brazos, which features double-wall insulation. The stainless steel Brazos is designed to keep drinks cold for up to 20 hours.
The Clarity performed surprisingly well at insulating when out and about. I had doubts it would provide much insulation because of the, well, clarity of its glass design. Despite this good performance, on a very hot day in full sun, I’d still opt for a more opaque canteen.
AVEX Bottle Other Comments
The AVEX bottles passed some of my daily use tests with flying (and vibrant) colors. They all fit nicely into my car’s cup holders. (On this note, the Autoseal Technology is great in the car. It’s fantastic for sipping while keeping one hand on the steering wheel. Which, I understand, is recommended.)

The AVEX bottles fit easily into cup holders for on-the-go use.
The bottles also slid into my backpack’s exterior water bottle pockets and stayed put without leaking.
Additionally, when put to office duty, they didn’t take up much precious desk space or leave rings from leaks on my desktop. The double-wall design of the stainless steel Brazos inhibits condensation and sweating. This model would be my top choice for desk jockeying.
In sum, the AVEX bottles performed exactly as you’d expect high-quality water bottles to perform and did so with panache. The lifetime warranty against defects that comes along with an AVEX bottle adds some nice peace of mind.
It is important to note that these bottles are not large-capacity water carriers. At 20 oz. to 25 oz., they can run dry in a hurry when paired with high temperatures or strenuous activity.
AVEX Bottle Color
According to the current listings on the AVEX website, the following colors are available for the bottle styles I’ve tested:
Brazos 24 oz. stainless steel: Black and Stainless.
Brazos 25 oz. plastic: Blue, Charcoal, Citrus, Orange and Pink.
Clarity 20 oz. glass: Electric Green, Berry and Ocean.
Who AVEX Bottles Are For
The AVEX bottle lineup satisfies the need for form and function. The materials and engineering are thoughtful. The colors are bold and modern. Moreover, the performance and functionality of the Autoseal Technology are excellent and add some techy fun to the water-drinking experience.
The lineup of AVEX bottles offers a range of choices for various types of water bottle users. For those craving convenience, the plastic 25 oz. Brazos bottle is a good fit. For those seeking refuge from plastics, the Clarity is the clear choice. For those with an eye on aesthetics, the 24 oz. stainless steel Brazos couldn’t be more attractive.
People wishing to put hot liquids or carbonated beverages in their canisters will have to look at bottles in the AVEX lineup not covered by this review. The Brazos and Clarity bottles I tested are not for filling with hot or carbonated liquids.
MSRP 24 oz. stainless steel Brazos: $29.99.
MSRP 25 oz. plastic Brazos: $14.99.
MSRP 20 oz. Clarity: $19.99.
