Camelbak 70 oz. OMEGA Reservoir

"Easy to fill, easy to drink and easy to clean. The new Omega HydroTanium reservoir is the culmination of years of research and customer feedback. The extra large opening is big enough for ice cubes and big enough to get your hand in for cleaning. Durable "burst-resistant" polyurethane construction, a worry-free, leak-free HydroLock to shut-off the flow of water when needed and the PureFlow delivery tube keeps water tasting like water, not plastic. Includes BigBite Valve."
