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

Perfect size for my running belt and used on short runs.

These are very practical and confortable to carry once the liquid is finished.

This is the only soft flask I’ve ever used, and it’s been excellent. It fit perfectly in my running belt during a backyard ultra and stayed comfortable the entire time. Drinking from it was easy with great flow, even while moving. It’s also simple to clean, which is a big plus after long runs. Overall, it’s a reliable, no-fuss soft flask that does exactly what it should.

I’ve been using these 500ml soft flasks for running and hiking, and overall I’m really happy with them. They’re lightweight, easy to squeeze, and collapse down nicely as you drink, which helps reduce sloshing. They fit well in my hydration vest and don’t bounce around during runs. The material feels durable and flexible, and I like that they come in a 2-pack. The cap seals tightly and I haven’t experienced any major leaks, which is super important when carrying them in a vest or pack. The only reason I’m giving 4 stars instead of 5 is that there was a slight plastic taste at first, but after a few washes and air drying, it mostly went away. Also, you do need to make sure the cap is screwed on carefully to avoid small drips. Overall, great value for the price and perfect for races, long walks, or travel when you need something compact and lightweight.

Leak-proof, Lid functionality

Works well, but the plastic has a strong flavor and you can smell it. My daughter won’t use it because “the water tastes funny” which I can’t argue with. Makes me concerned it is leaking chemical into the water? Aside from that, would have given it 5 stars.

Perfect and easy to use while running!

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.
