The Nalgene Easy Sipper has been the most requested product we have had over the years.  Most people love the convenience of the wide mouth bottle when it comes to filling and cleaning but sometimes find it hard to drink from.  The Easy Sipper solves that problem.  It fits snugly into the neck of the bottle and your beverage flows out in a nice controlled flow.  Then its easy to pop the Easy Sipper out to clean or fill your bottle.  Its the best of both worlds.  Dishwasher safe. The Easy Sipper comes in the same colors as our 63 mm Loop-Top Closures; Fits 32oz Wide Mouth Nalgene bottles only
