THESE ARE IDEAL FOR A HYDRATION VEST!The two flasks fit great in the pockets of my hydration vest. This brand does make a compatible one as well. Easy to use. Easy to fill.

This works. I don’t particularly like it though.First, there is nothing wrong with the bottle. I added filtered water. Chilled it. Then drank from it.It imparted not taste to the water, which is a relief because most soft materials do.It is comfortable to hold.It has measuring markers, though I can’t see the use. I mean, yes I’ll know I have X milliliters left, but … why?While the soft side is comfortable to hold, and it is designed to fit in the pouch of a running vest, I would still prefer there was some sort of strap to keep it from falling from my hand. Accidents happen. In fact, because it is designed for a vest, I would prefer it had a strap from the vest to the bottle. Again, to protect against drops.The spout is a bite-down and suck method. Nothing wrong with that, and it works. But because of that, I don’t use these for running. I just don’t prefer to bite down and suck while I’m running. Walking, sure, it’s a more leisurely pace.I think it’s a good product, just not my cup of tea.

I carry a hydro pack while I was out snowboarding to keep me hydrated. However, when I spending time in the snowboard park, the hydro pack can get in a way as it is a little too heavy for hitting the jump and obstacles. These 200ml soft water bottle are so handy as it fits my snowboard pant pockets perfectly. The package came with two 200ml water bags. It is easy to use and no leak. I highly recommend this product.

UTOBEST 200ml Soft Flask, 2 Pack Flexible TPU Hydration Water Bottle, 28mm Caliber in Marathon Purple: I consider the quality of the material to be mid-weight and durable. The bottles arrive with the mouthpiece sealed in plastic. I tested each bottle and found the following: no strong plastic smell, doesn't leak when turned upside down or squeezed. To drink water, tilt bottle upward and bite the cap, this will give you a stream of water. Easy to fill up by unscrewing the entire cap. These are great for walks or hiking to avoid carrying additional weight. To dry these out, I placed a chopstick inside and stood the bottles up. The 200ml are the size of a pen.

The perfect "event" flask. Folds down almost flat (except the lid), and is very easy to use and light to carry. I got the mid sized one so it'll hold enough fluids for at least one or two drinks. Or it can be used to carry water for a pet or child. No matter what it's used for, it's a handy item to have around. So much easier than carrying a large cup or bottle around. This one is small enough to fit in most pockets, bags, purses, and even some wallets. Very versatile for sure. I hope it last a long time, we shall see. Overall, a pretty cool idea.

It's quite the cute bottle, although it won't get seen much tucked away in my vest. I got the 500mL size in the design in green, almost as easily seen as the yellow. It's a little longer than the flat bottomed one that came with the vest. It easily sits in the standard water bottle pocket of running vests.The top comes in two pieces, the screw on bite valve and a dust cover. The dust cover is tethered to the bottle and fits on the bite valve tightly enough that it is essentially tethered during filling. No losing the top. The back has measurements if you want to really dial in your water amount.It is TPU, which adds a bit of flavor after a few hours. It's slightly less than others, but anything that's been in there a day really needs to be purged and rinsed and replaced.

The collapsible soft bladder water bottles are great for skiing & snowboarding. I used to carry a metal flask in my jacket pocket but saw a fellow boarder using these & had to try them. They are very lightweight and easy to fill. The thick silicone bladder is sturdy but flexible - plenty strong enough to hold up to landing on it in a tumble. The spout heads have nice easy flow and snap closed for a super watertight seal - no leaks. I love how they compress as I sip - less volume & weight I have to carry as the day goes on. They are easy to fill with a large opening & the cap on the spout is attached to the bladder no worry about loosing it off the ski lift. Pretty easy to clean - I just rinse them with hot water as soon as I get back to the cabin. Very happy with their form, function & durability.

I love the size of it. I packed one for a trip and the other stays with my bike. They are fairly simple to keep clean and easy to use. They store very small.
