CamelBak Reservoir Dryer
With the CamelBak Reservoir Dryer you can dry your reservoir quickly and completely with this design. The dryer has two pieces, the first piece has a hanger and clips to the tube port while the reservoir is upside down.
The second piece fits inside the OMEGA opening and also clips to the drinking tube, allowing the water to drain out of the OMEGA opening as it hangs.
While you can bend a coat hanger to hold your bladder open while it dries, this does a much better job. Worth it.
