How much longer does a rotomolded cooler keep ice compared to a standard one?

A rotomolded cooler keeps ice roughly 2–3 times longer. Standard coolers hold ice 1–2 days in moderate heat, while rotomolded ones last 3–5 days, and top brands push 5–7 days if not opened constantly. The difference is construction: rotomolded coolers have a seamless shell with thick polyurethane foam and a heavy rubber gasket that seals properly. They’re expensive, but worth it for multi-day trips; for a picnic, save your money.
