The CORE Magnetic Leak Proof 12 Can Soft Cooler is a mid-capacity insulated backpack cooler designed for casual outdoor gatherings—picnics, beach trips, and tailgates. It holds 12 cans and features a waterproof zipper and magnetic closure for added leak resistance. The bag uses insulated padding to maintain cold for several hours and includes a leakproof liner. It's crafted from durable, water-resistant exterior material with padded carry straps for comfortable transport. Best suited for day trips where portability matters more than extreme ice retention. At ~$100, it positions itself in the mid-market segment between budget cooler totes and premium brands like YETI. The magnetic clasp is a practical differentiator for one-handed operation.
