The CORE 36-Can Magnetic Leak Proof Soft Cooler is a mid-capacity insulated backpack cooler designed for casual outdoor use—picnics, beach trips, and tailgating. It features a waterproof zipper and leak-resistant construction with a magnetic closure system for added sealing. The cooler holds approximately 36 cans (roughly 28–30 liters) and uses standard foam insulation to maintain cold temperatures for typical day-use outings (estimated 6–12 hours). The padded backpack straps and insulated exterior make it wearable for hands-free transport. Key build details include a welded seams design, TPU-lined interior, and water-resistant exterior fabric. Extras include a bottle opener. Best suited for families, casual campers, and social gatherings where portability and leak protection matter more than extreme ice retention. At $140 (with current discount), it occupies the mid-market segment—above budget value picks like Tourit, below premium brands like YETI.
