We all know the problem.  Those wide mouth Nalgene bottles are awesome.  You can get way more than liquid in there.  From applesauce to ice cream, they're a backpacker's friend. 

But what about the other 90% of the time when you carry liquid.  They're hard to drink from without getting a dunkin'.  Well, here's the solution.  Guyot Universal Splashguards fit easily into the opening of wide mouth lexan bottles to make drinking easy (and dry) again.  You can even fill the bottles without removing the SplashGuard, but they come out easily for washing.  Available in several attractive colors.  Dishwasher safe.

The Guyot Universal Splashguards fit most all the major brands of 32 oz widemouth lexan bottles including Nalgene.  They're more flexible than the standard Splashguards to allow them to adjust to the minor differences in bottle mouth size.   Also, try the Mini SplashGuard that fits in your 16oz Nalgene widemouth or N-Gen bottles!  Great Escapes offers the Universal Splashguards in all the same great colors as the standard along with many more to express your individuality.
