Ice Retention

Ice Retention starts with the cooler construction. Legend Coolers are made with that same tough Roto-Molded constructed used in Whitewater Kayaks and other top quality coolers. Our coolers have up to 2 or more inches of pressure -injected closed-cell polyurethane foam insulation throughout the lid and walls. A airtight rubber freezer style gasket is used to lock in the cold.  

Ice Retention: It's pretty simple if you put ice into a hot or warm cooler the ice will melt trying to cool down the cooler and its contents. So...

  • Pre-Chill your cooler with ice or frozen water bottles. The old gallon milk jug filled with water and frozen works great, plus it can be used over and over. When possible load cooler with cold drinks and food to reduce your ice from melting.   
  • Its best to completely fill the cooler with ice to maximize ice retention after adding food and drinks. After contents have cooled add more ice if needed. 
  • Ice that is wet, has already started to melt and will not last as long, reducing the coolers ice retention time. 
  • Ice that is below the 32 degree freezing point and dry will last much longer, optimizing the ice retention.
  • Keep the cooler in the shade and out of direct sun light when possible. If not cover the cooler to provide shade.  
  • Opening the cooler will allow the cold air to escape and warmer outside air in reducing the coolers ice retention time. 
  • A mixture of Block and Cube ice works well. Frozen water bottles and block ice melt slower thus allowing the bag or cube ice to last longer.
  • Please read the information below for Safe Handling of Dry Ice before use in cooler.

  • Unscrew and Remove the Vacuum Release Button from the front of the cooler before using Dry Ice. Our coolers are Airtight!!!


Caution: Keep Dry Ice away from children if they cannot be closely supervised at all times.

Dry Ice temperature is extremely cold at -109.3°F or -78.5°C. Always handle Dry Ice with care and wear protective cloth or leather gloves whenever touching it. An oven mitt or towel will work. If touched briefly it is harmless, but prolonged contact with the skin will freeze cells and cause injury similar to a burn.

Store Dry Ice in an insulated container. The thicker the insulation, the slower it will sublimate. Do not store Dry Ice in a completely airtight container. The sublimation of Dry Ice to Carbon Dioxide gas will cause any airtight container to expand or possibly explode. Keep proper air ventilation wherever Dry Ice is stored. Do not store Dry Ice in non-ventilated rooms, cellars, autos or boat holds. The sublimated Carbon Dioxide gas will sink to low areas and replace oxygenated air. This could cause suffocation if breathed exclusively. Do not store Dry Ice in a refrigerator freezer. The extremely cold temperature will cause your thermostat to turn off the freezer. It will keep everything frozen in the freezer but it will be used up at a faster rate. It is the perfect thing if your refrigerator breaks down in an emergency. There are also Commercial Storage Containers available.

Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide. If the concentration of carbon dioxide in the air rises
above 0.5%, carbon dioxide can become dangerous. Smaller concentrations can cause quicker breathing and headaches but is otherwise not harmful. If Dry Ice has been in a closed auto, van, room, or walk-in, for more than 10 minutes, open doors and allow adequate ventilation before entering. Leave area containing Dry Ice if you start to pant and breath quickly develop a headache or your fingernails or lips start to turn blue. This is the sign that you have breathed in too much CO2 and not enough oxygen. Dry Ice CO2 is heavier than air and will accumulate in low spaces. Do not enter closed storage areas that have or have had stored Dry Ice before airing out completely.
