Buite 500ML Soft Flask, Portable TPU Soft Flask Running Bottles for Running Vest, Hydration Pack - Ideal for Hiking Cycling Climbing(Blue）

I travel quite a bit for my work. I have basically a "Mobile Office" in my back pack which has my laptop, a second screen, kindle scribe, battery packs, chargers, etc. etc. etc.I used to also carry a water bottle, but that has now become my blender bottle. I am not a fan of single use plastic water bottles, yet I really don't have any room left to fit in my backpack.Bam! This water bottle comes into play! I don't have one of those athletic chest strap thingies because I'm pretty basic when I go for a jog. This though, I can shove it in a tiny nook when I need to go from place to place, then when I arrive, it's super easy to fill up and it doesn't leak. When I'm done I just smoosh it back into my backpack and I'm ready to go!It's a little bit of a pain to get that little silica gel pack when you first get it, but that's such a minor inconvenience. This thing is sweet and allows me to hydrate while bringing along my mobile "command center" as I have dubbed my set-up.

I’m only on my second refill (threw the first one out) and though the plastic taste seems to be less than it was on the first fill, it is still noticeable. Perhaps it will further dissipate with more refills, if it doesn’t I will not continue to use it.I’m not a hiker or really much of an outdoorsman, I use it to keep by the bed at night when I wake up with dry mouth. Very convenient and doesn’t spill or drip. The bite valve works great.If the plastic taste doesn’t go away after several fillings, I’ll edit this review, lower the star rating and pitch the flask!

This is a great little flak. I got this for snowboarding because I saw others with this kind of water bottle and it's so smart. Your able to carry the bottle in any pocket and it fills down to almost nothing once your done drinking. I had another bottle for running and that one spoiled all over me when I tried to drink from it, so now I carry this flask with me instead when I go running. I like the way the mouth piece works, it's impossible to spoil water on yourself.

I ordered this collapsible water bottle for me to be able to carry extra water on my long bike rides. Since it is soft sided and can be rolled up, I figured it would be perfect for fitting into my jersey pocket. Unfortunately this is going straight into the trash.Immediately when I opened this up, I noticed droplets of something inside the bottle, and upon closer inspection notice spots of an oily liquid on the exterior of the water bottle's neck (I tried to capture that in my photo). It's clearly not water because it didn't evaporate while sitting in the packaging, and it has a greasy/slick feel to it. And upon opening up the bottle (the bite valve cap was sealed with a plastic shrink wrap), there was one of those desiccant packets inside the bottle, but the packaging on the desiccant packet looks like it is sort of oily, maybe as if the manufacturer tried to use it to absorb oil inside the bottle.There's no way I'm going to put drinking water into this bottle after receiving it this way. I'm totally bummed that this is the product I received, but hope that I can save someone else from making the mistake that I made.

Had high hopes for this flask, but there's just ones design feature that was a little off for me. I intended to use this for travelling (esp on the plane), short walks and hikes where I might need water but didn't want to bring a bulky water bottle. This looked ideal. This is essentially a hydration bladder, but way smaller. Generally, everything is ok, except for the bite valve. For the bite valve seem difficult to tell when it was locked or open, which is kinda important when you're carrying this inside a backpack with dry things. The bite valve is surrounded by a single, plastic shell that makes it difficult to tell if it's extended and open or closed. That's really the only down side for me, but it was a pretty important feature.

If you prefer lightweight backpacking, this is the perfect 500 ML hydration container. It collapses to a very small size as you consume the contents and it weighs very little. The cap is attached with a tether which ensures that it does not get lost. This cap helps keep the mouthpiece clean.It's a little large and flopping for running, but for slower paced backpacking or hiking it's great!

The media could not be loaded. I was looking for more compact water carrying options for running or hiking. This works out pretty well. The valve works to keep in water (see video). Easy to work the bite valve. If I take care to squeeze out the air, sucking on the valve gets water out even without turning it upside down (i.e. I don’t need to squeeze or use gravity. but I’ll probably still squeeze the bottle to make it work better). It has a bit of structure at the bottom to help in maneuvering it into a bag pocket or a running belt pocket which I appreciate as well. Does what I hoped it would do, and I expect to bring this on runs, hikes, and travel in the future.

I recently bought my dog a backpack to take on our hikes. I then ordered this 500 ML (2 cup) portable flask to carry his water in. The flask is a perfect fit in one of the pockets and amazingly, does not leak even when laying on it’s side. I have his collapsible bowl, treats and his ball on the other side for weight balance. The flask itself is constructed well, collapsible, has a no leak nozzle and easy to carry. Great find and great fit!
