I'll have to look later today. It's a 35 qt Coleman or Igloo Extreme 7 with a silver body and white lid. I start with a block of ice I freeze fill it with goodies and top off with crushed ice. As the week goes on I take things out and add more. Drain water when needed and add more ice. After a week long trip there is still some of the block left when I get home.
My son has the 45 qt Extreme 5, silver/blue body with white lid. Doesn't hold ice very well.
