Injection-molded cooler vs rotomolded cooler: For occasional use, save your money and get the injection-molded one
Rotomolded coolers are built like tanks with thick insulation and days-long ice retention, but they cost $200–$500 and weigh a ton. Injection-molded coolers like the Coleman Xtreme hold ice for 24 hours, cost $50–$100, and are much lighter. The trade-off is durability — injection-molded can crack if dropped — but for occasional tailgates or beach trips, that risk is low.
