The 10 Best Hydro Flask Accessories in 2022

---

After debuting just over 10 years ago, Hydro Flasks quickly gained traction as the go-to insulated water bottle.  For many people, the simple benefit of having a bottle that is vacuum-insulated was enough of a selling point.  For others, it's the clean, yet stylish design.  Whatever the reason, Hydro Flask continues to build its following and shows no signs of slowing down.

It's only natural what happened next.  A whole range of accessories have been developed with the goal of making life with these amazing but cumbersome bottles a little easier.

We here at BottlePro got involved in this niche early with our cup holder adapter, so we've seen it grow over the years, including new notable accessories coming available fairly often.  Here are some of our favorites for the best accessories for Hydro Flasks in 2022 (focusing on 32 and 40 ounce bottles).

ACCESSORIES FOR GETTING AROUND

The most common accessories for Hydro Flasks involve making it easier to bring your bottle wherever your adventures take you.  These include cup holders, bottles slings, and handles.

---

#1: Cup Holder Adapter

Swigzy

As mentioned above, BottlePro's first product on the market was a cup holder adapter for large bottles, including Hydro Flasks.  But even though we have our own product in this space, it's hard to argue with the amazing product that Swigzy has put together.

See our separate post for a full recap on cup holder options.

​This recommendation may change when we release our planned BottlePro v3, but for now, we think Swigzy is the best, most versatile cup holder adapter on the market today.

Honorable Mention for Cup Holders - BottlePro

Our current BottlePro version is adjustable and can fit most cup holders on the market.  It's not quite as premium and versatile as Swigzy, but that's also reflected in the price.

​So if you're looking for a cup holder on a budget that still fits a wide range of situations, give us a try!

#2: Stylish Bottle Sling

Hydro Flask's Bottle Sling

Hydro Flask doesn't make a very wide range of accessories in general outside of their bottles, containers, and lids, but they do make a great bottle sling.

These carrying pouches fit the Hydro Flask aesthetic for obvious reasons, so they're sure to complement your bottle's look.

​And they're also lightweight and packable so you can avoid carrying around extra ounces on your travels.

#3: Heavy-Duty Bottle Sling

Wild Wolf Bottle Sling

For a heavier-duty bottle sling, it's hard to go wrong with Wild Wolf Outfitters' carrying pouch.  If you're more into utility than the aesthetic look, then this is a fantastic option.

The military-grade pouch comes with multiple pockets and thicker padding on the shoulder strap.  The pockets in particular are one of our favorite features since it makes day-hiking much easier.  Just stash your keys and phone in the big pocket and you're set!

#4: Leather Bottle Sling

HikerPouch

If you're looking for a carrying pouch that's more premium and different from the rest, then consider HikerPouch.  This is one of products, and we're really proud of how it turned out.

We decided to make HikerPouch because there were a multitude of pouches made of neoprene and synthetic fibers, but we wanted a leather option for a more natural feel and to cut back on plastics.

HikerPouch includes a pocket for your phone and an extra D-ring for flexibility (either clipping your pouch to something else, or clipping on something like a carabiner key ring).  We're also planning to add strap color options very soon, so stay tuned!

#5: Paracord Handle

Slolife

Rounding out our 'Getting Around' category is paracord handles.  We love the Slolife ones in particular.  Just attach it under the rim of your Hydro Flask, and you're good to go.

​With 29 available color options, you're sure to find something that fits your bottle's look.

It's also packed with a surprising number of features.  The handle includes a compass, whistle, and has a carabiner attachment that makes it super easy to clip onto your backpack or anything else.

There is also a flintstone and blade (meant for creating chips for sparking fires), but we haven't independently tested how well these actually work.
​

ACCESSORIES FOR PROTECTION

Next, consider investing in something that can help keep your bottle looking great for years to come.

---

#6: Bottle Sleeve

Thermi

A bottle sleeve can be a great insurance policy against inevitable drops and slips.  The Thermi silicone sleeve can give you the peace of mind knowing that your bottle will be better protected from denting and damage.

And not only is your bottle protected, but you'll be less likely to drop your bottle in the first place because of the added grip.

​With 11 available color options, it shouldn't be hard to find a good matching (or complementing) color for your bottle.

Side note: if you're purchasing a cup holder adapter for your bottle, double check that your bottle + sleeve combination can still fit whichever cup holder you use.
​

#7: Bottle Boot

Hydro Flask Boot

If you don't like the look or feel of a full-bottle sleeve, then consider getting a bottle boot.

Hydro Flask has a silicone boot option that is a great add-on for your bottle to give it more protection on the bottom, which is where damage would be most likely to occur in the first place.

​Currently Hydro Flask has 6 available color options.
​

ACCESSORIES FOR FLAVOR AND ICE

Now that your bottle is easier to bring along with you on your adventures, it's time to think about ways to improve what you're actually drinking!

---

#7: Flavor Infuser

FlavorFuze (Original)

These are some more of our products, but we think you'll love them.  FlavorFuze lets you get creative by adding any fruit or other flavoring to your bottle.

Personally, these cool infusers have helped me drink more water because it tastes better.  And I was also finally able to stop my soda habit, something I'd been trying to do for over 10 years!

FlavorFuze Original (pictured) has a silicone lid that fits snugly in the neck of Hydro Flask wide mouth bottles.  The lid acts as a splash guard, so you can keep flavoring your water while taking a few sips.

See FlavorFuze Pricing on Amazon

​FlavorFuze Straw

My personal favorite. It clips onto Hydro Flask straw lids like this one (not Flex Straw lids).  The Kit  (link below) comes with a straw lid too!

See Pricing

FlavorFuze Steel

For making cold brew coffee.  We're releasing an improved FlavorFuze Steel shortly, along with Steel Mini that will be better sized for loose leaf tea.

See Pricing

#8: Ice Alternative

Ice Cube Sticks

At first, these Ice Cube Sticks might seem unnecessary, but they can be more handy than you might think!

They are a lot simpler to grab out of the freezer and drop into a bottle, compared to using ice trays or breaking apart ice cubes.

Easy to use, clean, and re-freeze.  And they won't dilute your drink if you're enjoying flavored water or some other kind of beverage.
​

#9: Splash Guard / Ice Stopper

SplashPro

Another one of ours.   This is one I've used almost every single day since making these handy little devices.  It's a great ice blocker and is tremendously helpful for taking sips of water while on the road and has kept my shirts dry.

There are some other great splash guards on the market (looking at you Guyot), but most are designed for Nalgenes and are just barely too small to fit Hydro Flasks securely.  It's only a 1mm difference in diameter (we measured it!), but it's enough to make a difference.  They also get pushed down by the Hydro Flask cap design.

SplashPro is our solution for Hydro Flasks.  The thin-wall allows you to add your Hydro Flask Flex Cap without pushing down the splash guard.

ACCESSORIES FOR CLEANING

It's not the sexiest category, but you should certainly put some thought into cleaning your Hydro Flask.

---

#10: Brush Kit

Mosolan

It's hard to find a more complete kit than this one.  It includes:

1. A large brush to fit down into your big Hydro Flask.
2. A thin brush for cleaning straws.
3. A small brush for the finer details, like around the rim of the bottle.
4. Tools for organizing and storing your brushes.

​You'll have plenty of tools in the tool chest to keep your bottle clean and worry-free.
​

Bonus: Bottle Tablet Cleaners

Bottle Bright

We almost didn't include these because our list was getting too long, but they're too useful to leave out.

In addition to regular brushing and washing, Bottle Bright cleaning tablets are good to use every so often to give your bottle a deep clean.  They can help with stains too if tea or coffee is your style!

The tablets are biodegradable, chlorine free, and environmentally safe, so you don't have to worry about using them.
