Breaking in your Hopper™
Like a good pair of boots or a quality baseball glove, the Hopper™ takes a little time to break in.
The extremely durable materials of the Hopper™ can make it feel rigid when first put into action.
Loading and unloading contents will become easier as the materials relax with use.
Caring for the HydroLok™ Zipper
The HydroLok™ Zipper is the best cooler zipper in the world, and with a little care and
maintenance can last a lifetime. As noted below, we recommend long term storage with the
zipper in the fully closed position to help protect the U-Dock™ seal. We also recommend regular
application of the included zipper lubricant – especially when putting into storage – by carefully
applying the lube to the U-Dock™ front, back, and inside.
Draining and drying
To drain water from the Hopper™ without spilling your contents, leave the HydroLok™ Zipper
slider just short of the U-Dock™ and invert the cooler.
Everyday cleaning
When your cooler gets a little muddy or grimy, a mixture of dish soap and water should do the
trick. Rinse with fresh water, then thoroughly wipe the inside dry with a cloth or paper towel.
Leave the HydroLok™ Zipper open for several days to ensure all moisture has dried.
Do Not Machine Wash. Do Not Dry in an Oven.
Storage
Make sure your cooler is completely free of moisture. It is recommended that you leave the
HydroLok™ Zipper in the closed position – with the slider fully pulled into the U-Dock™.
This will help protect the waterproof seal and the U-Dock™.
UV Exposure
You may find colors of the Hopper™ fading over time. This is a normal part of the wearing
process and will not aect performance in any way. Like your favorite YETI hat, color-fading
adds a little character.
