Hydrapak has been at the forefront of innovative bottle designs for the past 20 years.

What makes them special is they bring out all these new, crazy and functional designs but still manage to keep their price low.

Here you’ve got a super lightweight, collapsible 4-liter bottle, perfect for hiking, running or camping expeditions!

What I Liked About It:

  • How crazily portable it is! After you’ve finished drinking you don’t have to lug around some bottle in your bag that takes up a load of space. You just flatten it, roll it up and boom it’s tiny!
  • Not only is it super compact it’s also ridiculously light and can even be attached to your bag with the four lashes on both sides. So, all in all, it’s just crazy easy to carry. Oh, and did I mention it comes with a 4×4 inch carry bag that it fits in when folded up?
  • It also has a flexible handle that comes in handy either when pouring liquid out or when you’re filling your bottle up from a river.

Who’s it For?

If you like things compact and you like saving space, this is for you.

Especially if your an ultra runner or a serious athlete these can be really handy.

What Makes a Great Hydro Flask Alternative?

What Makes a great Hydro Flask alternative

Style, price, and functionality.

They’re much cheaper and a lot of them frankly look cooler.

But focus on what’s important. Find one that does what you need it to.

That keeps your drinks hot or cold for extended periods of time.

Water capacity

Varying in size from 16 to 32 ounces. Pick a size right for you and remember there’s nothing worse than realizing your coffee cups too small.

Thermal insulation

Thermal insulation

The best insulation is stainless steel with some kind of air pocket. This can keep hot drinks hot for up to 12 hours and cold drinks cold for 24.

Wide mouth option

This makes it easier and quicker to fill up from taps or rivers.


Being lightweight is important, you’ll feel that extra weight after a long days walk.

BPA Free

Every bottle on my list is free from BPA, stay away from that stuff it can have real nasty long-term effects.


Another important feature to keep a look out for, is what measures have been taken to make it leakproof. The best bottles on the market now will never leak.

Portable and packable

Portable and packable

Some of these collapse down to much smaller sizes. Seriously handy if you want to pack compact.

Handles and Straws

For personal preference, some of the containers have handles and straws. They’re not necessary but some people like them.


Some of these you can accessorize with different caps and lids. To be honest, I like the basic ones that come with everything you need, but that’s just me!

Dishwasher friendly

Dishwasher friendly

You’ll save yourself a shed load of time in the long run if it’s dishwasher friendly.

Definitely, something to look out for.


You don’t want to buy one of these and it breaks 6 months down the line. Buy from a reputable brand that has good reviews and it should last you years and years.

FAQ Section

What is inside of these mugs? Stainless Steel?

Most are designed using double vacuum stainless steel. This means that there are two layers of steel with a pocket of air between the two.

This enables them to maintain the temperature inside the flask while still being super strong and hard to puncture.

Can it be used with the tea infuser?

Yes, they can!

What is the bottom dimension for fitting into a car cup holder?

Most car cup holders are 3.5 inches to 3.8 inches in diameter. If that’s what the bottom of your flask is, you should be able to fit it in

Can I put wine in any of these tumblers?


It’s absolutely fine to put wine in any of these tumblers, just make sure you give them a good wash after.

Some are fine to whack in the dishwasher others you need to hand wash, depending on the model.

How long does coffee stay hot in any of these containers?

Depending on the model and quality of container it will stay hot for 4-12 hours.

This is one of the reasons to make sure to get a thermos flask that has good reviews as the quality of them can vary considerably. It’s definitely worth buying from a reputable brand.
