500ml Soft Flask, TPU Collapsible Soft Water Bottle for Hydration Pack, Running Vest, Folding Water Bottle for Hiking Cycling Climbing-1Pcs, White

Really great mottle. No odor at all, no leaking. Drinking action is easy. The top shoulders of the bottle are slightly stiffer allowing you to drink without the bottle flopping but the whole thing really does roll up tiny. The middle size is smaller than I was able to envision but it fits perfectly into a coat pocket. Not sure who would need the smallest size except somebody who perhaps needs a little bit of liquid to take medicine.

Purchased to use during my recent marathon, as there were some "cupless" water stations and I didn't want to carry my handheld for 26+ miles. It fits perfectly in the side pocket of my FlipBelt shorts. Only took a few seconds to refill with 2-3 cups of water/electrolytes, so you can avoid the congestion at every water station.

Good quality, light weight great for running Only down side is that they are hard to clean inside

The small size is very useful on the ski slopes for kids to carry in their jacket pockets. Not bulky, light weight, easy to open, and never leaked when taken through low and high altitudes, but water did have a chemical taste. I washed with hot soapy water and let it air dry the first time and the water had a slight chemical taste. I did another round of washing/rinsing with hot soapy water and the again the water still had a slight chemical taste. It tastes almost like watered down cough medicine. My oldest kid and I didn't mind the slight taste, but my younger kids refused to drink from it. The size and function still outweigh the chemical taste, which I hope will eventually go away. I may try washing with cold water instead in case the hot water is bringing out the chemical taste.

Perfect size and the quality is what I expected. Durable and best value.

Unsure of how to rate as I returned without use. I returned it because it smelt just like a brand new pool inflatable or really most any pvc plastic item. It was very strong smell. Everything I've ever owned that was an inflatable that smelled like that also had a taste to it. That I would tolerate to inflate but I didn't think I would like drinking out of something that smelled and tasted like that. I also haven't know that taste or smell to fully go away, fade for sure but not really gone. Would it flavor the water too? I don't know. That said if I was desperate cheap and needed something really small like this for water I'd manage it. I could probably deal with it. I went with a collapsible silicone bottle instead. It was bulky and heavy compared to this. Too big for my mini purse unlike this. It had no taste issues or smells and seemed more durable and had a clip so I could hang it from my purse. I guess pick your poison 🤷‍♀️

Bought the 250ml size to put in my BC pocket while scuba diving. One particular shore dive in Dania Beach, FL has a long walk to the site so this is perfect to use. Since it is a bit valve, I stick it in my BC pocket and am able to drink from it if I get thirsty while scuba diving.

This product is not good. The water bottle imparts a bad taste to the liquids. I tried water - tasted bad (and it was filtered water). I also filled one with pickle juice and the smell of pickles permeated the container; making the outside smell like pickles. I washed the outside of the container in case it was due to me spilling the juice while filling (which I know I didn’t do) and within an hour the pickle smell return. Something is wrong with this product. Other, similar, water bottles made of TPU did not have this same result. Guess I’ll go back to those.
