First, remove your HyFLO™ Bite Valve from your shutoff valve.

Next, insert the base of the Bite Valve Cover over the tube, and push it all the way down.

Open the top of the Bite Valve Cover, and re-insert your HyFLO Bite Valve onto the shutoff valve with the base of the Bite Valve Cover between the bite valve and the shutoff valve.

Last, close the top of the Bite Valve Cover. Voila!

The Big Zip™ EVO Connector Kit is a nifty accessory that allows you to filter directly from your GravityWorks™ into your Big Zip EVO without ever having to remove your reservoir from your pack.


To do so, you first need to remove your drink tube from your reservoir via the quick-disconnect. Then, plug the connection point on the connector kit's hose directly into the quick-disconnect point (you will hear a click). Next, attach the connector kit's hose to the base of your GravityWorks filter cartridge. Let gravity do the rest, as you're now on your way to clean, taste-free hydration.

Our Reservoir Cleaning Kit comes with two brushes: one long, thin brush and one shorter, wider brush. These are used to scrub different parts of your hydration reservoir.


The long, skinny brush is made to clean your drink tube. Keeping a finger in the hoop at the end of the brush, you can use the brush on the opposite end to scrub the inside of your drink tube. Note: When detaching your drink tube to clean, it's easiest to access the interior of your drink tube through the end with the bite valve.


The shorter, wider brush is used for scrubbing the interior of your reservoir. Simply hold on to the obvious handle, and use the bristled end to scrub at any visible dirt or residue inside your reservoir.


You can read our blog post on how to give your reservoir a deeper cleaning here.

To install your Drink Tube Insulator with the Big Zip™ EVO in your pack, follow these steps:

  1. Unzip and open the zippered portion of the Drink Tube Insulator.
  2. Inside your pack, disconnect the drink tube from the reservoir via the quick-disconnect attachment. Remove the disconnected drink tube from the pack.
  3. Feed the quick-disconnect end of the drink tube through the zippered portion of the insulator sleeve until the bite valve is centered in the covered, zippered area.
  4. Thread the quick-disconnect end of the drink tube and the non-zippered end of the insulator sleeve through the hydration access point at the top of the pack, positioning the bite valve within the zippered end in the desired location along pack shoulder strap.
  5. Reconnect the drink tube to the reservoir via the quick-disconnect attachment point.
  6. Secure the Drink Tube Insulator to the pack shoulder strap using the hook and loop fastener.
