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

I purchased the 500ml and that's the best purchase I've ever madeThe price is right in comparison to those high price tags from other brands and they do the exact same thing if not better.No leaks, seals perfectly fine and the best of all super easy to carry them .I normally take them on my vest or belt specially for those long runs. I freeze them during the hot summers here in Texas .They are also so durable and easy to wash .If you are looking for a flask . Look no further, give them a try and for the price 😉 you will be blown away.
