PerpleHydrapak Ultraflask | Collapsible Water Bottle 500ml | Soft flask for Running Vest, Belt & Pocket | Easy Open Speed Fill Cap | High-Flow Bite Valve for effortless drinking

i took it on a hike with me, and its nice that when it finishes you can just put it in your pocket folded and it doesnt take up that much space. highly recommended if you go on hikes or go to school.

This is probably the weirdest concept of water bottle I have seen ever. Weird but surprisingly very clever and functional. It is fully collapsible flask which is made of bag. When full, doesn’t make difference however when you drink it then you can fold it and it takes very little of space in backpack. I have to admit however it was a bit tricky to hold it, I needed to use both hands to hold bottom and on the cap. Very interesting concept, not fully convinced especially not at this price.

Odd, yet remarkably smart and practical. It's a completely collapsible flask crafted from a flexible material. When it's filled, it looks like any other bottle, but as you sip, it can be folded down, taking up minimal space in your backpack. I must confess, though, it was somewhat challenging to grip; I found myself needing both hands to stabilize the base while unscrewing the cap. It's a fascinating idea, but I'm not entirely sold on it, especially given the price tag.

Although this is a 500ml bottle, when it's empty it barely takes up any space, as it's made from a soft rubber material and can be folded up nicely into a small package.once ready to use, unscrew the cap and fill it up, once full, it feels just like any other water bottle, it doesn't leak nor will you squeeze it all over the place, it feels and acts just like a normal water bottle but with the benefits of once you're done, you can just fold it up and pack it away neatly as to not take any space.I've used it for a while now and it still works fine, it's not weakened or anything.For the benefit of portability, i have to recommend it, if carrying a full sized empty bottle is cumbersome, than this one will solve that.

Here we have a completely collapsible bottle.It come as is with a card label around the neck.The nozzle is soft, so rather than pulling it up to drink, you bite on it.It tastes a bit funky so I think I didn't wash it enough, so I would recommend washing it very well.The plastic on the top feels very solid, but bordering on brittle, while the rest of the bottle feels very thin. All that said, it's held together well so far, so this may just be the sign of a very compact bottle!

I am a long distance runner and water bottles are a big deal to meThis is a half litre bottle with a bite and suck head.It is convenient to the extent that once you have emptied it, you can fold up the main section as you run and stash it with a little difficulty as it has a rigid section where the wide head of the bottle screws onto the main section and the drinking head of the bottle is entirely rigid which leaves it unsuitable for pockets but does mean you could put it away in a small bum bag.Potential but expensive solution to the inconvenience of carrying water.

good foldable flask bottle.easy to fold.the quality feels adequate and perfect on the go.the bottle is also good looking in addition.the ml markers are especially helpful when you have to mix sachets or powders with water.

Ideal water container for emergencies or occasions where you do not want to throw the bottle away.
