camelbak come with different bladders 70 oz 100 oz ect
depending on the model. I have the camelbak Mule Woodland Camo 540 cubes 100 oz bladder and the BFM OD Green 100 oz 2550 cubes. Military styles being more rugged than the outdoor styles such as the rimrunner.try camelbak.com for more details on the models you are looking for. 100 oz being about 3 qts they will both hold several survival items Hope this helps.
