How long does a Yeti Roadie 24 keep ice in direct sunlight?

About 24 hours in direct sun on a hot day before ice turns to slush. Yeti’s “up to two days” claim assumes shade, pre-chilled contents, and minimal opening. Dark colors absorb more heat, so shade, a towel, or reflective cover helps, but physics still wins. For a full weekend with no shade, bring dry ice or extra ice bags.
