Vapeur de remplacement Vapeur (1,8 L)

What can you really say about a water bladder.
Easy to fill, easy to empty
Not sure how long the flap inside will last as you have to 'unhook' it during each clean, just have to wait and see.
As described you can turn it inside out which makes it easyish to clean. All bladders are a pain to clean and dry, this is certainly one of the less annoying ones. You still have to pull out corners and stuff with paper (as per instructions) to make sure areas dry properly.
I'd prefer a slightly shorter tube. It does flap a bit, and requires a bit more sucking to get the fluid, but that's just a preference.
All in all it's worked well, doesn't slosh too much on my back even when not full. Emptied completely on my last run, I.e. the suction works well to not leave some at the bottom, and very easy to use.
