JTReviews Raiting: 5 out of 5 Stars!
The WeyTy Hydration Bladder 2L EVA Leak Proof Water Reservoir is a very high quality replacement hydration bladder. It uses a dark gray EVA rubber plastic similar to military grade Camelbak bladders. This WeyTy Hydration Bladder uses a water filling port similar to the newer Camelbak OMEGA fill reservoir. This much larger fill reservoir is much easier to fill and clean then the old canteen style fill reservoirs. The fill reservoir also features a molded in handle for ease of filling and a hook for mounting it in a backpack or carrier. The fill reservoir features a retainer for the cap and easy to thread on cap with a deep turn knob. The WeyTy Hydration Bladder also features two mounting holes in the EVA body. The bladder features fill markings in .5L increments. The drink hose tube is also a dark gray color and does not feature an insulated cover but one could be added with ease. The hose is a nice length. The drink hose is mounted at the bottom of the WeyTy Hydration Bladder and features a nice o ring and a strong spring loaded clip to hold it in. The bite valve has an easy to remove cover. The bite valve itself is much different then a Camelbak as it has an internal hard plastic core. While new to me this may turn out to be a nice addition. I know many people complained about the Camelbak bit valve took some work to open up properly at first. This one is ready to go! At 2L it is smaller then my Camelbak OMEGA. But that is ok! I usually don't drink the last 3rd liter. So this will save me weight. Note: because of the OMEGA style fill reservoir this may not fit in early style military carriers.
