We recommend wiping your pack with a damp cloth to remove dirt. If the pack is extremely dirty and needs a deeper cleaning, soak it in cool or warm water with a very mild soap. Rinse the pack thoroughly with cool water. If soap residue remains in the fabric, it may create suds if exposed to water or sweat.

DO NOT wash your pack in a washing machine. Machine washing may damage the pack or affect the integrity of the fabric and fasteners, and will void the Got Your Bak™ Guarantee.

The best way to care for your reservoir is to clean and dry it after every use, especially if you fill the reservoir with anything other than water. However, if a reservoir has not been cleaned after every use, and mold or discoloration develops:

1. Use hot water and a CamelBak Cleaning Tablet. Or use 2 tablespoons of baking soda or bleach instead of CamelBak Cleaning Tab. Mix the solution inside your reservoir and elevate the reservoir above the tube and Big Bite Valve. Pinch the bite valve, allowing the solution to flow into the drink tube and fill the bite valve.

2. Let the reservoir and cleaning solution sit in the reservoir and drink tube for about 30 minutes.

3. Wash the reservoir with hot water and mild soap. Be sure to completely rinse away the cleaning solution in the reservoir and drink tube before using again. You can also use CamelBak brushes from our Cleaning Kit to scrub your reservoir and drink tube. Brushes are the best way to ensure you are scrubbing all of the areas of the reservoir clean.

4. Once the reservoir is clean, be sure to air dry overnight so no moisture is trapped inside, which can cause mold to grow.

These steps will make your reservoir safe for use. If there are still spots left behind, these are permanent mold stains that may not be removable. However, your reservoir is still safe and usable after you’ve cleaned it.

    Comments about CamelBak Ultra LR™ Vest:

    I got this new pack just in time for this years Big Sur Marathon. I saw the forecast was going to be warm and knew I could use all the capacity I could get.

    I did not have a chance to test it out prior to the run so I was a little nervous about trying something new on a run of this length. Thankfully I was plesently suprised. No chaffing, very little pack movement, no breathing restriction, enought room for my shell jacket/food/etc, and most importantly for big sur plenty of water.

    Two notes 1). The retention straps for the front pockets kept slipping loose with a full water bottle(3/4 full was no issue)and 2)It helps to keep the load in the front pockets balanced so the pack does not pull to one side.
