The CORE Magnetic Leak Proof 18 Can Soft Cooler is an insulated backpack cooler designed for beach trips, picnics, and tailgating. It holds 18 cans with a waterproof zipper and leakproof magnetic closure system. The cooler features a welded liner for leak resistance and is made with durable insulated materials suitable for day-use outings.
Capacity & Insulation: 18-can capacity (approximately 12L), typical soft-cooler foam insulation rated for moderate ice retention (6–12 hours in warm conditions).
Build: Waterproof zipper, magnetic leak-proof closures, welded interior seams, and basic insulated exterior shell designed to minimize leaks when upright.
Carry: Backpack-style straps (construction and padding not fully detailed in source, but standard for category).
Who it's for: Casual beach-goers, car-camping families, and tailgaters seeking a lightweight, hands-free cooler option without premium pricing. Best for day trips rather than multi-day expeditions.
Trade-offs: Moderate ice retention and mid-tier capacity; typical soft-cooler durability at a competitive price point.
