Insulation and ice are great, but they can only go so far when it comes to keeping your cooler cold.
Even Superman has to deal with Kryptonite at some point, right?
Luckily, there are super easy ways to make your cooler stay cold for a longer period of time:
1.Pre-chill the food and drinks you plan on packing.
2.Fill the cooler to the top with food and drinks.
3.Freeze bottled water to store in empty spaces.
4.Store your cooler out of the sun.
5.Put the ice in last.
6.Don't drain the water when the ice melts.
7.Pack all the essentials on top.
8.Keep the lid closed.
