PRO TIP:
MAXIMIZING ICE RETENTION
A YETI® Cooler, with its roto-molded construction, heavily insulated walls
and lid, and freezer quality sealing gasket, provides remarkable insulating
performance and ice retention capabilities.
To get the most from your YETI’s insulating qualities, we strongly recommend
you read the concepts outlined below. These techniques are used by seasoned
outdoor professionals who rely on extended ice retention.
Start with a cool YETI Cooler
A cooler is designed to insulate, which
means it will retain heat as well as cold.
For this reason, try to store your cooler
in a cool environment prior to loading
it with ice. If stored in direct sunlight,
a warm garage, or a hot vehicle prior
to use, a significant amount of ice will
be wasted cooling the cooler itself.
One way to cool the walls is to pre-
load it with a sacrificial bag of ice. The
starting temperature of the cooler is
one of the most commonly overlooked
variables in ice retention.
Dry ice provides 3x the cooling power of regular ice, leaving more room for contents. Unlike
ordinary ice chests, which crack when exposed to dry ice, a YETI Cooler is designed to stand
up to this extreme temperature. Consider using dry ice in any
situation where extended cooling power is necessary, such
as long trips or power outages. It can be used by itself or in
conjunction with regular ice.
Dry ice must be handled with protective gloves to prevent frostbite. It will likely freeze the
contents in the cooler and can cause aluminum cans to rupture. Keep dry ice away from
small children. Ventilation is extremely important. With improper ventilation, the gas
emitted from dry ice can cause shortness of breath and loss of consciousness.
Freeze or pre-chill contents
Chilling or even freezing the contents you
intend to load into your cooler is an often
overlooked way to extend ice retention.
Consider that it will take over 1 lb. of ice to
cool a six-pack of canned beverages that
started at room temperature.
More ice is better
We recommend filling your cooler
with as much ice as possible. Ideally, you
want to have an ice to contents ratio of 2:1.
Please keep in mind that when two YETI
models are completely filled with ice, the
larger of the two will retain ice longer.
USE DRY ICE

Not all ice is created equal
Ice can get much colder than its freezing point. “Warm” ice (near 32°F) is typically wet
to the touch and dripping with water. Cold, sub-zero ice is relatively dry and will last
substantially longer.
