NoNamewrote a review of Platypus Big Zip LP Hydration Bladder on July 24, 2013
Familiarity: I've used it several times
Nice piece. Like Source's/Camelbak's bite better, but the rest of the package is better here. This do probably not leak as quickly as the Source (regular bite) (?time will show?). Like especially that the container is clear / transparent. It is easier to clean this way. The quick release and open/close is very good.
