The CORE Magnetic Leak Proof 18 Can Soft Cooler is a mid-capacity insulated backpack cooler designed for casual outdoor outings. It holds 18 cans with a waterproof zipper and magnetic closure for hands-free operation. The cooler features a leakproof liner and insulated construction suitable for day trips to beaches, tailgates, and picnics. It includes padded backpack straps for comfortable carry and weighs moderately when packed. At $114.99 (discounted from $129.99), it occupies the mid-range price tier. CORE is a recognized outdoor brand with steady customer feedback, though it lacks the premium reputation of YETI or RTIC. Real-world reviews note solid ice retention for 8–12 hours in moderate conditions, functional waterproof zippers, and comfortable carry for short trips. Some users report occasional minor seepage under extreme tilt, and the straps can feel thin when fully loaded. Best suited for casual beach days and family picnics rather than extended backcountry camping.
