Tired of going out for a day or weekend trip only to have your ice melt in the first couple of hours? Problem Solved! These chests will maintain ice for 9-10 days in 90 to 100 degree heat with 5% of the ice still remaining. Made out of a 100% Grade "A" polyethylene inner and outer skins with a high density polyethylene foam injected in-between to make for the most cold retentive boxes in the world! The 100% food graded rated internal liner is non-staining, non-odor absorbing, and impact resistant. Double insulated lids to maximize ice retention. Ultra heavy duty, self supporting hinges and lockable heavy duty latches. Integrated molded grab rails for carrying on the cube chest and a strong, nylon rope to grab and carry on the long chests.
