Review on FITLY Soft Flask - 12 Oz (350 Ml) - Shrink As You Drink Soft Water Bottle For Hydration Pack - Folding Water Bottle Ideal For Running, Hiking, Cycling, Climbing & Rigorous Activity (FLASK350) by Tom Plowman

Pros: 1) I wanted something small that my husband and I could carry in our pockets during our daily 5 mile walks. This is perfect. As you can see in the pic, it is slim enough to put in your back pocket.2) We freeze them with the water inside (leaving room for expansion), so it is extra nice on a hot day to have what is basically an ice pack. The pic shows the water frozen inside. I like holding my bottle against the back of my neck to cool me off, and it speeds up the melting process so that I have some water to drink fairly quickly. My husband keeps his in his back pocket for most of our walk, so his remains partially frozen the entire time, but he still has water to drink.Cons: 1) I can’t get the spout to work. I know you’re supposed to bite the soft part gently but even when I do that, squeezing the bottle gently, barely anything dribbles out. So I just remove the cap and drink it that way. No big deal — I like getting a bigger swig of water. It doesn’t drip out of the spout, so that’s good. My husband can drink out of the spout with no problem.2) There is a slight rubber taste. Like drinking out of a rubber ball. I washed the bottles with baking soda and water, and it helped a bit. My husband doesn’t notice it as much as I do. But if you add some powdered, flavored Pedialyte to the water, then it tastes great and it gives you more electrolytes too!These bottles were perfect for our needs despite the cons.
