Hydro Flask Flex Boot Review: Is it Worth It?

Hydro Flask sells a silicone flex boot which is designed to slide onto the bottom of your Hydro Flask bottle and protects it from dents and scratches that come with everyday use.

But does this flex boot actually work and is it worth the extra cost?

Hydro Flask bottles dent easily especially on the base and the silicone flex boot stops the majority of these dents and scratches. If you're rough with your Hydro Flask or you've got kids using it I would absolutely recommend the flex boot.

What Does The Hydro Flask Boot Do? Does It Work?

The Hydro Flask Flex Boot is made from silicone and slides over the base of your Hydro Flask.

It's fairly easy to get on and off but it won't slide off unless you intentionally pull it off so it'll always be protecting your Hydro Flask.

I got a Hydro Flask Boot when I purchase the 12 oz Hydro Flask Kids bottle. It came free and honestly I didn't think a lot of it and probably wouldn't have purchased it myself if it didn't come free of charge.

But after 12 months I can honestly say that is has been a completely lifesaver for my Hydro Flask.

At the same time I also bought an 18 oz Hydro Flask with no boot and my kids used it and took it to school and look at the damage it received. First a small dent in the bottom, then absolute destruction.

After just a few months the base of this Hydro Flask was damaged so badly that the vacuum seal broke and we lost the insulation.

The Hydro Flask no longer keeps drinks cold for an extended period of time and we can't get it replaced under warranty because it's our fault it was broken.

Compare this to the base of the 12 oz kids which we've had for the same amount of time and has also been used a lot by my kids.

As you can see apart from some minor scratches the base is still in pristine condition. So yes the Hydro Flask Flex Boot absolutely works and does the job.

How Much Does It Cost? Is It Worth It?

Given Hydro Flask water bottles are already expensive you can be forgiven for wondering whether or not it's worth paying the extra money required to get a Flex Boot.

The Flex Boot comes free with the 12 oz Kids Hydro Flask bottles however unless you're buying a kid's one you'll need to purchase your boot separately.

Luckily they aren't that expensive. Both the small and medium sized boots are the same price and at less than $10 each they won't break the bank.
