DryGuard eliminates water overflow caused by a faulty bottle.
It works! Standard feature on the Sierra cooler, DryGuard can be retrofitted on any Crystal Mountain, Alpine,Glacier, Mirage or Mogul cooler. Get that "Cooler Confidence". It's like buying inexpensive insurance.

How Does the DryGuard work?
The co-injection molded gasket creates an airtight seal inside the reservoir. In the event of a cracked bottle, the manual float shuts off the airflow, preventing water from escaping the reservoir.

5-micron Air Filter:
Protects against airborne contaminates from entering the water.
