The Hydro Flask 24 oz Standard Mouth is a portable, insulated bottle that is sleek, stylish, and feels comfortable in hand. We were huge fans of this 24-ounce bottle, so much so that it narrowly missed receiving our Editors' Choice Award. We used the Hydro Flask day in and day out, for both hot and cold beverages, and in both urban and outdoor settings. The lid is easy to clean, the bottle fits in cup holders and bike bottle holders, and it works well for both hot and cold beverages. We found that the bottle is typically better for cold drinks because of its tall, narrow dimensions. Like other Hydro Flasks we have reviewed in the past, the Standard impressed us with its durability and simple overall design.

Our Analysis and Test Results
Ease of Use
With a smaller capacity than the Hydro Flask Wide Mouth, the 24 oz Standard Mouth is a lighter, more versatile option that still has all of our favorite features of a Hydro Flask bottle. The carrying handle is smaller than that of the Yeti Rambler and the Hydro Flask Wide, since the Standard has a narrower mouth than both of these bottles. We didn't find this to be too problematic since we were able to still fit two fingers into the handle comfortably. The narrow mouth was also nice for drinking cold beverages; wider mouth bottles are tough to drink from one-handed and also cause backsplash, especially when drinking and walking simultaneously!
We did not like the narrow mouth for hot drinks, though. The narrow mouth of the Hydro Flask seemed to conduct heat, making it almost impossible to drink our hot drinks hours after the bottle had been filled. On the opposite end of the spectrum, the narrow mouth was too narrow to fit ice cubes for cold drinks. If you are planning to use the bottle as simply a water bottle, the Hydro Flask Standard is a great option, but for hot drinks or very cold drinks, it falls a bit short. The narrow mouth also makes this bottle challenging to clean. The fact that the threads are on the outside of the lid helps its case a bit, but it is still challenging to get it completely clean.
Over the years, Hydro Flask has proven to make bottles that are built to last, and this one is no exception. We took this bottle to the crag, we biked around town with it, we dropped it on the ground. Though the paint got a few nicks in it, the bottle was otherwise unscathed after a few months of heavy use. While other insulated bottles saw minor dents and chipped paint, the Hydro Flask stayed relatively unscathed.
We do admit that part of this is the luck of the draw and how the bottles fell. Many of our friends have Hydro Flasks and Klean Kanteens with several dents and scratches. These dents and scratches haven't affected the performance of any that we have heard, though.
The Hydro Flask Standard Mouth has a much lighter feel that previous Hydro Flask models we have tested. Its sleek shape, narrow width, and slightly smaller capacity give it this light feel. It's more than a feeling, though — the Standard weighs significantly less than our Editor's Choice award winner.
The Hydro Flask did well in this metric. We filled this bottle with coffee, tea, Emergen-C, and water, and for the most part, flavors seemed to dissipate quickly after a wash or two. The threads on the lid are exposed and easy to clean, which is where we found flavors to linger the most. That said, it is easy to clean, which gave it a higher score in this metric.
In terms of value, Hydro Flask products are a bit of an investment. They are not cheap up front — the Standard Mouth bottle costs $35. Comparatively, the Wide Mouth 1L is $40 and the Yeti Rambler 26 also costs $40. All of these name-brand vacuum insulated bottles cost a pretty penny, but they do seem to last. The Standard, due to the grievances mentioned above, felt like it had a hefty price tag for a bottle that we ended up using for room-temperature water most frequently.
Though we listed some complaints about the Hydro Flask 24 oz Standard Mouth, overall, we thought this was a great bottle. When leaving the house, our hand gravitated toward this bottle more often than not, whether we were going climbing or heading to the coffee shop. Though it has a hefty price tag, the Hydro Flask is a durable, reliable product. We also loved that the bottle comes in a wide variety of color options and sizes.
