Rolls up and doesnât take up much space. No leaking for me.
100% recommend. Got it to use while at universal studios. No issues, no leaks. Easily rolled up to fit inside my belt bag or even in my smallish pockets of my shorts. It was a little awkward to hold at first. Also recommend getting a clip if doing a lot of walking.

How does this compare to the name brand competitor?
How does this Zelvot Soft Flask compare to its main name-brand competitorâthe Hydrapak Soft Flask?
Material:
The main soft body material is fairly similar. They are both made of a more rubbery, silicone-like material unlike the plastic water bags of yesteryear. However, the Hydrapak soft flask uses noticeably thicker material than the Zelvot soft Flask.
Cap:
Both flasks have a similar harder plastic portion that leads up to the threaded cap. The Hydrapak soft flask has a slightly thicker plastic section than the Zelvot soft flask. The bite valves are similar quality. I like that they Zelvot soft flask comes with a bite valve cover. Some Hydrapak soft flasks have a speed fill cap but I personally don’t prefer this.
Seams:
The Hydrapak soft flask has cleaner, nicer seams than the Zelvot soft flask. You can only barely see in some of the description photos for the Zelvot soft flask, but the seams stick up and away from the body of the soft flask itself. The Hydrapak seams are relatively smooth and seamless.
Price:
For a 500ml soft flask, the Hydrapak soft flask comes out to $17-20 while the Zelvot flask comes out to $10. Is the Hydrapak worth nearly double the price? Hard to say. I’d imagine that the thicker material of the Hydrapak soft flasks would help it last longer, and the robust Hydrapak warranty would likely help with peace of mind. But, if you want to save some money, this Zelvot soft flask works great.

Collapsible, no leaks, good flow rates
This is a review for Running Vest Soft Flask, BPA-Free 500ml Collapsible Water Bottle for Hydration Backpack, Folding Running Water Bottle for Running Hiking Cycling Climbing (White, 500 ML)
I’ve come to prefer collapsible water bottles like this. No more sloshing of water to ruin a nice quiet run or hike. Partially filled rigid water bottles always seem to make annoying sloshing sounds as you hike, jog, or run. I’m glad to have that problem solved.
If I were doing it over, I would probably order the blue one. This white (translucent) one’s not bad, but I think the blue one would be even better.
The capacity is 17 oz or 500 ml, but I was able to fit more in. If you’re very careful, you can fit about another 50 ml in.
The bite valve works well, and it has a better flow rate than most of the others I’ve tried. You can also remove the cap and get even more flow.
The material is made out of is very flexible, much more so than some of the other collapsible water bottles (like Platypus). I much prefer this material.
I can’t vouch for long-term durability, but so far it’s been great, and it seems to me that it should last a long time if taken care of properly and gently. I don’t see why not. I’ll update if things change.

Silicone Flask
This soft silicone flask works well for carrying during activities. Its unstructured body makes it a winner to stick in a backpack for a run. Unlike metal or plastic bottles, this doesn’t stick out making an uncomfortable dent in your back. It molds to you so you can stay hydrated and comfortable on the track or whatever activity you’re doing. It’s easy to fill and easy to drink from., and the protective cover stays attached so you don’t drop it.

The classic build for these, works well
This is the typical build for these Chinese bottles, it has the same bite valve you find on all these products. The valve is good: it doesn’t leak, and it dispenses water at a decent rate. The polyeurethane seems strong enough to put up with some abuse, and the coloring is simple. I recommend it. It’s a good size for a vest, or even to tuck in a running belt for some bounce-free water storage.

collapsible and easy to drink out of it
I absolutely love this water bottle as it is extremely lightweight. It is really easy to carry. I can easily put it in the side pocket of backpack. The bottle is leakproof and easy to drink out of it. It can be collapsed to fit small space.

Perfect and lightweight
We normally run with our club on Saturday mornings and go for about 10 miles. We have water stops on our runs with water fountains. I put these in my belt without water and put electrolyte power in there and fold it up. Somewhere around mile 6 or 7, I will fill it with water, have my drink and can finish out my run. When I am done, fold it back up and put in my pouch again. They hold in your hands nicely and you bit the tip just a bit and squeeze to get the water from it. I have about 3 of these now and they all work perfectly!
