1. Grip bag by its closure with both hands, laying thumbs over the grip tabs. Keep index fingers on the tracks of the seal.
2. Squeeze and kink closure into both palms, forming and "S" with hands offset.
3. Bag will pop open easily. This technique becomes easier with a little practice.

Closing:
Make sure closure is clean and properly lubricated with silicone spray or similar lube. If in the field and none of these are available, use oil, saliva or water in the closure tracks as necessary.

Cleaning and Lubrication:
This closure provides a very close-fitting rubber seal. It is therefore necessary to occasionally clean and condition it to maintain ease of use and reliability. Thoroughly clean tracks.

• Spray lubricant/ protectant (we recommend 303 aerospace protectant) on to brush and thoroughly brush into full length of closure.
• Snap closure together and pull apart a few times to evenly distribute lubricant/protectant.
• It is recommended to store closure in closed position to prolong time between cleanings.
• If lubricant/protectant is not available, similar products are effective. In the field, any lubricant, saliva, or water will work to help close the tracks if they are dry.

Closing:
Make sure zipper is clean and properly greased. If it is unusually difficult to close, use a grease stick to thoroughly lubricate zipper tracks.

• Leave last 2 to 3 inches open. Squeeze bag to purge air. Finish closing zipper, making sure slider goes all the way to the end stop. Give bag another squeeze to ensure proper closure.

• Depress valve end, use to remove any remaining air. Release valve, turn valve lock counter-clockwise until it firmly rests against valve end. Stow valve under valve cover.

Cleaning & Lubrication:
The drysuit zipper also depends on close fitting rubber to provide a reliable seal.

1. Use a toothbrush and water to thoroughly clean zipper teeth.
2. Any sand or grit can compromise seal.
3. Lubricate with a Grease Stick.

Do not use any other type of lube on this zipper!
It is recommended to store closure in closed position when not in use.
