This my third Camelbak and it does not inspire confidence. My rucksack was damp and the bag emptier than I expected after the first day's use, probably caused by a leak where the tube joins the bladder. The tube is now easily detached by pressing a button, so it's likely that this was pressed by other gear during use.
My last two sprung leaks after only a year each, but continued with the brand as Cotswold kindly provided this one as a free replacement.
I've heard good reports about platypus, get that instead
