Hydrapak’s recently unveiled Reversible Reservoir II turns the backpack bladder drink system inside out. Believe it or not, that’s a good thing. The updated design incorporates Hydrapak’s patent-pending Slide Seal, a plastic slider that fastens over a wide-mouth reservoir constructed of durable polyurethane. The wide, top-loading reservoir not only makes adding ice cubes and sport mixes a cinch, it can also be turned inside out for complete cleaning and drying, meaning those tasty cold beverages will taste like they should. The Reversible Reservoir II ranges in size from 50 ounces to 100 ounces (MSRP: $25.99-$29.99) and features a push-button connector that allows the drink tube to be removed for spill-free filling and easy cleaning, capped off with the softest easy-open bite valve on the market.
