The LBX Tactical Hydration Pouch is a simple home run product made out of 500d Cordura making quite lightweight compared to generic 1000d pouches. The pouch is covered with MOLLE from bottom to top which only adds a little weight in exchange for great modularity allowing you to put more pouches on your LBE as needed. The closure flap has full coverage with a huge amount of Velcro allowing you to put plenty off patches on it. The inside has 3 hanger pieces to support your bladder if you feel it necessary it is also not padded or insulated just the 500d cordura to keep it lightweight and cheap. NOTE the only problem I've ever had with this pouch is Source bladders handles are a tiny bit wider than the pouches mouth making it necessary to work it in a little.
Plenty of MOLLE making it quite modular
Plenty of Velcro for pouches
Simple and effective
Source bladders are a little wider then the mouth of the pouch making a little bit difficult to get it in the pouch
