YMMV Review

I had never heard of Avex Water bottles until they contacted me before the Outdoor Retailer Show in January. Avex is part of the Ignite USA Company and make water bottles and travel mugs. Their products are not your run-of-the-mill solutions, rather innovatively engineered to provide superior performance.

Looking Inside the Bottle

Testing

I tested the Avex Highland bottle at work, in the car, on my bike commute, and in the pack when cross-country skiing. All the places I like to have hot liquids.

The Avex Highland Travel Mug has an innovative Autoseal technology to make it leaf-proof and spill-proof. This technology can be used with one hand with no lids to remove or spouts to open. All you have to do is press the button and take a sip. When not pressed the top automatically seals to prevent from leaking. The valve defaults to the closed position and has a locking mechanism for when you put it in your bag. The lid is made with an open architecture to make it easier for cleaning. It can be washed on the top rack of a dishwasher. The lid is durable and BPA-free.

Inside the Lid

The bottom bottle features Avex’s Vacuum Insulation. The bottle is double-wall stainless steel. Vacuum insulated mugs are constructed of two separate stainless steel walls. One wall forms the inside of the mug and one forms the outside of the mug. These two walls are carefully engineered to have a controlled amount of space between them. The air trapped in the space between the two walls is removed through a technical process, thereby creating a vacuum in that space. By creating a vacuum, the exchange of energy/temperature between the inside of the bottle and the outer air temperature is inhibited. Beverage temperature is retained for hours. Avex states that this bottle will keep hot beverages warm for five hours and cold beverages cold for 14 hours. The double-walled construction also prevents condensation from forming on the outside of the bottle.

The lid actually has two openings on the top that open when the button is pushed. One opens slightly to vent while the other is the larger one that you drink out of. The lid screws on to the bottle and creates a tight seal. You can feel it when you screw the lid on. At the base of the lid and at the bottom of the bottle is softer rubber type material. This material adds grip for the lid and base of the bottle. It helps the bottle grip a table top better as well. The bottle has a sleek shape to help it fit into smaller cup holders. I like the look of the bottle, it is smooth and sharp. I just wish I could have gotten the blue color. =) The bottle is not light weight but is not overly heavy either. It is about what I expected out of a double-walled stainless steel bottle.

In "Locked" Position

The bottle is made of BPA-free materials, but I was not able to find any information about sustainable materials or business practices. For these reasons, I gave it a rating of zero for sustainability.

The Avex Highland Travel Mug has been a good bottle thus far. It does keep liquids hot much longer than a traditional mug does. You will be surprised how hot your drink can be hours after you put it into the bottle. I found it worked well for cold liquids as well but since it is the winter, I used it for hot drinks much more. The bottle is dishwasher safe, which definitely helps get it clean. Since the lid has lots of nooks and crannies in it the lid is kind of difficult to get clean by hand. I have also noticed that the lid kind of holds onto strong scents unless you clean it in the dishwasher.

Top of the Lid

The bottle has been very durable for me. While I have only had it for a couple of months, I have not had any issues with it yet. The best part of the mug is how easy it is to use. Since the bottle has only one button to push, and you can do it with one hand, there really is not much to do but push the button. The bottle does a good job insulating both hot and cold liquids. The lid is where the mug loses most of its insulation. The Autoseal technology has worked nearly flawlessly. I have not had any leaks or issues with the button. The lock mechanism keeps your stuff safe if you need to put the bottle in your bag. The only issue I have noticed is the drink opening will hold a small amount of liquid in it after you take a drink. I had to make sure to suck up that little bit to make sure it did not spill anywhere. Apart from this no other liquid ever got out.

Overall ★★★½☆

Overall, the Avex Highland Travel Mug has been great for warm drinks this winter. I was a bit leery of the Autoseal mechanism, but it has worked well. I really like the gripper material that they used on the lid and at the base. These are some of the added features that set this bottle apart from others I have. The double-walled construction is both solid and effective. If you need a bottle for insulting liquids, I would definitely recommend these. They come in two colors and two sizes. It is a bit on the heavy side, so I think it is best for daily use or day trips. I would not use something this heavy on a backpacking trip. The bottle retails for $23, which is similar to other bottles of this kind. As always, your mileage may vary.

Pros

  • Double-Wall Insulation
  • Streamlined look
  • Autoseal Technology works
  • Gripper material on the lid and base

Cons

  • Collects a little liquid in the drink hole
  • Hard to hand clean

  1. I just wanted to add to this review — I bought this bottle in July 2012. I love it – leakproof, kept my coffee hot, one handed operation. 2 weeks ago my beloved mug began leaking. The origin of the leak was behind the locking button. It started as just a few drips, and wound up over two weeks progressing to the point where I was carrying my coffee mug to work in a gallon ziplock bag (this look doesn’t win ‘cool’ points!). I contacted Avex customer service, and they flat out replaced the entire mug for me. While I’m disappointed that the mug leaked, their customer service definitely keeps me happy as a customer and hopefully I won’t get unlucky again.

    • Thanks for the comment. Good to hear they covered the issue. Problems happen and hopefully it is an anomaly and not the norm. I continue to use mine without issue. Hopefully I do not get unlucky as well.

    I bought an Avex sport thermos recently (Nov 25th), in Jackson Hole, WY.
    I have used the thermos daily at 10,000 feet terrain levels, filled with hot coffee.
    The hotter the beginning temp of course, the longer the liquid will stay hot. So, be sure to start with hotter than you may desire to drink (180-200 degrees) at the moment, then open it later for a sip, as it will be very hot. It stays hot all day, and after 8 hours becomes warm. I find it supremely convenient to break out of my backpack, and am confident in not losing a grip on it, with it’s rubber-wrapped body.
    After using it for 20 days of skiing, at altitude, I have experience no leaks.

    Major Negative Point to Consider;
    Being an outdoor product, the design, as pointed out in the review above, fails in the difficulty of hand cleaning. I followed the instructions to soak the lid for 10 minutes in a dish soap cleaner. However, the internal components of the mouthpiece section show a serious build up of stain and build up from coffee and tea stains. I am residing in a cabin with no dishwasher, and quite often users of outdoor products are not capable of using dishwashers (I also use these types of products sailing).

    Therefore, I would advise that if you intend on using this product without access to regular automatic dishwasher availability, that you check with Avex on how to properly hand clean the device, because the instructions inside the bottle do not properly prescribe an effective cleaning method.

    Other than that, it’s a great bottle. I see it however, as a health risk without the ability to completely break it down and clean the mechanism. I don’t believe a dishwasher would be much more effective on the mouthpiece device, because it closes on one side and cannot be left open to clean in the dishwasher.

    A re-design is needed for a 5 star review. It works great, but it is not disposable at $23 plus tax, therefore it needs to be hand-cleanable.
