>>534042Osprey bladders are my favorite
I've used platypus, camelbak, ospreys and they seem to hold up the best. They don't have that weird taste you have to flush out when you get them and are relatively easy to fill with all the support that's on it. The only real complaint I could have with it is that the bite valve doesn't have a sheath or any means of keeping it clean from sand, dirt, etc. the magnetic sternum strap works ok, but is personally go with a clip instead. Just with any bladder system, they tend to freeze easily in cold weather even with the foam guard they sell. Overall best bladder I've used.
