WHICH HYDRO FLASKS FIT IN CAR CUP HOLDERS?
With the every-growing popularity of reusable water bottles like Hydro Flasks, more and more people are wondering what is the best way to keep their bottle close at hand on the road?
But which Hydro Flasks fit in cup holders, and do you need a cup holder adapter for your car? This can be a tougher question to answer than you might initially think because of the sheer number of cup holder designs and water bottle sizes.
We've developed this step-by-step guide to help you make the best decision for your situation.
And while this post is primarily focused on Hydro Flasks, it also applies to similar reusable bottles like Nalgenes, YETIs, Klean Kanteens, Iron Flasks, Thermoflasks, Takeyas, Simple Moderns, Fifty/Fifty, and many others that are on the market today.
LOOK AT YOUR CAR'S EXISTING CUP HOLDER
Before thinking about which Hydro Flask will work for you, we recommend taking a closer look at your car
First, measure your cup holder's diameter and save it for later.
Then, determine if you have a "standard" or "non-standard" cup holder according to the descriptions below. This can have a major impact on whether cup holder adapters would fit securely in your vehicle, which opens the possibility of using larger bottles.
WHICH HYDRO FLASK WORKS BEST FOR YOUR LIFESTYLE?
Now that you know whether you have a "standard" or "non-standard" cup holder, it's time to think about what size bottle you'd like to have. Keep in mind that the "narrow", "wide", or "oversized" designations below refer to the bottle diameter, not the mouth diameter. For example, you can have a 20oz Wide Mouth bottle that is categorized under "Narrow" because it is only 2.91" diameter.
The lists below are based on specifications listed on Hydro Flasks website and some that we independently verified. If you already have a bottle, we recommend measuring its base yourself to make 100% sure that you have the correct measurement. If your bottle has a protective boot, then you should also include this in the width measurement (they generally add around 0.25" to the diameter, but it varies based on the boot manufacturer).
The mug measurements are for the diameter of the body, not including the handle.
The links in the lists of bottles go to the product pages on Amazon.
There's a lot of information here, so to make it easier, we've developed this flowchart to help you sort through it all. You just need to know (1) whether you have a "standard" or "non-standard" cup holder and (2) the diameter of your cup holder compared the diameter of your desired bottle.
Disclaimer: The information provided above has been fact-checked against Hydro Flask and Amazon websites (and with some in-person measurements). The flowchart below is based on our experience and observations. However, please note that we cannot 100% guarantee compatibility of any resulting purchases you make because there are literally hundreds of thousands of different bottle/cup holder/adapter combinations once you add them all up. But hey, that's what return policies are for!
With that said, let's dive right in!
