I wanted to write a Hydro Flask review because I’ve had mine for a quite a while now and so far it’s one of the favorite water bottles that I’ve ever used.
I actually wrote a post about the best water bottles for travel, so I suggest checking that out if you’re looking to see all of the different options available, and my favorite one of the bunch is the Hydro Flask.
I’ve used Nalgene, Kleen Kanteen, Yeti and plenty of other different bottles before but it wasn’t until I found the Hydro Flask that I knew I finally had what I was looking for.
It’s an insulated bottle, so keep that in mind if you’re looking for a bottle to use if you’re participating in any adventure or action based activities where you might drop it, but other than that let’s take a look at my review.
In this post I’ll be talking about the 21oz standard mouth bottle but there are also a variety of different sizes and other options available online.
My Hydro Flask Water Bottle Review
When I first picked up the Hydro Flask I was surprised by how sturdy and solid it felt.
I was used to using hard plastic (BPA-free of course) or those metal bottles and although they felt sturdy I never really thought that they were too solidly designed.
The Hydro Flask is made from stainless steel and it’s insulated as well so it’s able to keep cold drinks cold (up to 24 hours) and hot drinks hot (up to 6 hours).
This way it’s good to use if you’re traveling or hiking during the summer and want a cool, refreshing drink or if you’re spending time outdoors during the winter and you want something to warm you up.
Like I mentioned above the bottle is designed from stainless steel and I find that this gives it a firm, solid and steady build quality.
I read on the actual website that it’s made from 18/8 Pro Grade stainless steel and that it takes advantage of a TempShield protection.
It’s an insulated bottle so on the inside is some insulation and you’ll want to avoid dropping it because there’s the possibility that the insulation can break and will completely lose its effectiveness if that happens.
At the top of the bottle is a large mouth opening but it’s not as large as those Nalgenes with the huge gaping hole at the top so I find that it’s just perfect for using to drink and it’s not so big that there’s much of an issue for overflow or spillage.
The lid screws tightly onto the bottle, it’s BPA-free and there’s even a loop built into it so it’s possible to attach to a backpack and just makes it easier to carry overall.
Speaking of carrying, I can grip the bottle (I have the 18oz) quite easily in my hand and thanks to its sweat-free powder coat finish it’s not that slippery even when it’s wet.
Is the Hydro Flask really that effective at keeping cold drinks cold and warm drinks warm for a certain period of time?
In my experience, yes!
I use the bottle for a wide variety of different things and I even use it as my bedside drinking option these days so that I’m able to enjoy ice cold water whenever I wake up throughout the night.
Even this past summer in Toronto where it was regularly very hot and humid I was always just tossing a handful of ice into the Hydro Flask and I loved being able to drink chilled water during the entire day.
I noticed that it will be able to keep drinks colder for longer if you’re not constantly refilling it but if you drink a lot and you’re constantly adding more water to the bottle then you’ll definitely notice that the ice cubes melt away a lot quicker.
As for hot drinks, it’s still summer when I’m writing this but this winter I definitely plan on adding hot tea, coffee and even hot chocolate to the bottle and using it to stay warm when I’m walking around and spending time outdoors.
So far I’ve noticed that I’ve been able to add ice cubes to the bottle in the morning or before I go to bed and they’re still there, although a bit melted, more than 12-hours later.
I haven’t myself been able to test the 24-hour claim but for me having cold water available for up to 12 hours at a time is definitely good enough.
Which Size Should You Choose?
There are a variety of different sized bottles and you can even choose from either a standard mouth opening or wide mouth opening depending on your preferences.
The wide mouth options come with a bigger capacity and if you’re heading into the backcountry or spending a lot of time without the ability to refill your bottle then it’s the wide mouth one that I’d recommend.
With the wide mouth you can choose from a bottle capacity of:
I actually don’t like the wide mouth because I have trouble preventing the water from spilling out onto my face and down onto my shirt so I prefer the standard mouth size bottle since it’s easier for me to use.
In this post I reviewed the 21-ounce standard mouth bottle just for perspective.
For the standard mouth size you’re able to choose from a capacity of:
The 21oz is my recommended choice since it’s able to hold just a little more liquid than a traditional 500ml water bottle and for what I need it for (light hiking, traveling, cycling) it’s just perfect.
