Great product.
You won't be disappointed.
I have been at odds with plastic hydration bladders for a decade.
I could never bring myself to suck in that awful plastic taste, even of the ones that say "no plastic taste".
This product is exactly what any normal person, or a firefighter needs.
Two thermos bottles side by side, directly connected is the solution, or you can use just one, for smaller missions.
Ice cold water at your tongue tip that actually stays cold, and no plastic taste.
I highly recommend this system, it's good quality, the self sealing bottle lids work flawlessly, and the mouthpiece is one of the best I have ever seen. With a sturdy cap and valve to keep it from leaking or getting dirty when dragged through the dirt.
All you gotta do is suck out the first warm water that sat in the hose, and you got fresh, uncontaminated ice cold water for at least 90 minutes or longer depending on how hot and dry it is.
Super happy with this awesome product.
Thanks team for making it.
