Review on Nathan 1.5L Replacement Bladder for Hydration Vests & Packs - Leakproof & BPA-Free! by Albert Tucker

NOTE: This cylinder/hose combo does not come with a black connector to snap the hose on. It is absolutely impossible to make an airtight seal. I thought the first one I received was defective so I sent it back. Unfortunately, the replacement they sent has the exact same problem. I don't know what people think of Nathan. There are no instructions on how to make a strong connection. DO NOT buy this product.
