Thermally insulated Evoc Hydration Bladder for backpacks - makes Evoc backpacks hydration packs.
Improved version and works better in colder air.
The nozzle freezes easily
As described, and has not frozen yet in sub-freezing temperatures.
purchased for my son and he loves it. no leaks!
I don't know if this has the so-called isolation has no function in real life. At least at 30 degrees below zero, I have caused the mouthpiece to freeze, even though I had blown the hose to nothing. The mechanism of the mouthpiece also likes to stay in the hand when removing the protective cap or turning the lock. I'd rather recommend Evoc's regular bladder without insulation.
A small and conveniently sized bladder. We haven't been able to test that insulation separately yet, but it's a solution that works in normal use in the summer.
Easy to maintain.
Seals very well, took me a while to figure out how to open it. No issues with this design…. Just not happy with the bite-valve hook-up. These hydro packs should ALL come with the magnetic bite-valve attachment across the chest buckle. I have hiked and biked for many years and I think the magnetic bite-valve attachment is superior to all others.
High quality and just what I missed. I recommend. Opening the bag may be confusing the first time, but it’s ridiculously easy. The answer was found using google, as many others had searched for similar information.
