Review on Osprey Packs Hydraulics Valve Cover by Mario Anderson

You can't beat this product. First Osprey unquestionably supports everything they do. Photo of product in clear packaging showing it has never been used B. Bite valve (sold separately)C. Cover (sold separately) I can't tell you the number of times I've been on the trail, dropped my pack and covered my mouth in mud. This solves this problem. It is also convenient to bend over to prevent your body and leg from accidentally pinching and opening the flow of water.
