Great bladder with one weakness
Great bladder, has not leaked on me so far.
The detachable hose feature is very handy.
Only thing I hate is the bite valve, it is too stiff to turn between on and off, which gets 10x harder if its freezing cold and requires you to take gloves off.
I took it off and replaced it with a camelbak replacement bite valve which is great and there's more water flow
