The best ever to keep functional, space-saving, very refreshing without attending

Great thing if you, wherever you are everywhere, can drink up to 3 liters of water and to only have to pick up the water bottle from the bag from the backpack without having to constantly stop. Great invention, the water in the bladder has been in my Deuter Futura 28 without thermal protection at 38 'C on Bali cool! I never want to miss even with all sports!
Intense plastic taste can exclude me, just few times with hot water rinse, ready! Not always the same no fussy be (other recessions), everything new brings a bissl odor or taste with them !!
The bladder can also provide well with together with the liquid in the refrigerator.
Strong buy recommendation !!!
