Rotomolded coolers vs injection-molded coolers: Rotomolded is overkill for a day at the beach

Rotomolded coolers are tougher and hold ice longer thanks to a seamless, thick plastic wall with 2-3 inches of foam insulation, but they’re heavy, expensive ($200+), and hard to carry. Injection-molded coolers like a basic Coleman cost $40, handle a weekend trip fine, and are lighter. The rotomolded advantage only matters for week-long off-grid camping or rough handling—for a few hours at the beach, save your money.
