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

Amazing Product, I bought this for when I go to trips and want something small that can fit in my pocket. I usually bring them to theme parks and fill them up with water at water fountains or free style machines. Quick purchase is saving me hundreds of dollars from buying those $5 water bottles at the theme parks. Highly recommend for thrill seekers

Fits perfectly in the front pocket of my hydration vest. I use it for electrolytes during long runs. So far no leaks. Light weight.

Great product!

Sometimes they are hard to clean out but good to take on a run or jog just don’t forget to clean it as soon as your done , also it took like a week to get rid of a plastic like taste when I first got it

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.

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.

Disturbing chemical taste after many uses. Otherwise very functional.

is as advertised but gives water a very bad chemical taste.
