I have one of the Black Camel Backs which was issued to me when I was active duty (Retired 2008) and have used it religiously mounted inside my huntin day pack. Never had a leaking problem, but only put water in them. That's the biggest mistake GI's always made with them. Once the sugar gets in there they will deteriorate from the inside out.
Yes the Camelbak brands are the best you get what you pay for IMOP.
I use the heck out of mine.
We got them from Cabelas the pak has tons of storage and the 70 oz bladder is plenty.
That has more storage potential than mine but I do prefer it over a daypack.
I use the heck out of mine. I got one at WalMart that came with a nice back pack and the bladder in it.
Here is a piece of advice. DO NOT put anything in it except water. The sugars in sports drinks will turn into mofongo if its not all rinsed out. I had to throw away the first bladder due to that
I use mine moreso in scouting preseason stuff than I do in season, but I do use it some in archery
Mofongo.
