Review on TRIWONDER Collapsible TPU Soft Flasks For Hydration Pack - Ideal For Running, Hiking, Cycling, And Climbing Sports Water Bottles by Kyle Ahmed

Product is ok. It had a funny taste in one of the bottles. Maybe after the second use it will be better. Holds water and no leaking on first run and that is good. Hard to drink from, you really need to bite down on it. This will become a bigger problem on hotter days. It suits my purpose and if they become problematic they may be frozen toss away on 1/2 marathons or marathons. This may seem like a negative review but it is not. I am not used to soft bottles and this may be just ME learning how to run with them. It does not deserve anything less than a 4 star for my impatience. Good job.
