Durable high quality replacement water bladder

The Raniaco Portable 2 ltr water bladder is strong and durable. For us we use our water backpacks in the summer months. It's really hot outside especially riding a dirt bike, or breaking down, either way all anyone every wants us but water. We typically replace them after they sit thru the winter months, for apparent sanitary reasons. Not anymore this will fit in every water pack or does ours.
