Rotomolded cooler vs standard cooler: Rotomolded keeps ice 2-3 times longer

Rotomolded coolers last 3-7 days vs 1-2 days for standard ones. The key difference is construction—rotomolded has a seamless shell with thick polyurethane foam and a sealed gasket, while standard coolers are blow-molded with thinner foam and weaker seals. Worth it for multi-day trips, but overkill for a picnic.
