【4-Layer Advanced Insulation Keeps Cool Longer】 This cooler backpack features a professional 4-layer insulation system: 600D Oxford shell, 5mm white cotton fabric, PEVA fresh-preservation film, and a leak-proof PEVA liner. As a premium insulated backpack, it locks in cold for up to 16 hours (or retains heat for up to 10 hours). Whether you need chilled drinks for a beach day or warm snacks for a camping trip, your food stays fresh all day long.
【No More Messy Spills】 No more melted ice leaking into your car trunk. This leakproof cooler backpack is built with a seamless PEVA inner liner and water-resistant double zippers, creating a fully sealed barrier. Even when ice melts, every drop stays inside. The smooth surface wipes clean in seconds – no odors, no stains. Double-stitched seams are built for extended everyday use, making it a reliable insulated lunch bag for work, travel, or outdoor adventures.
【Spacious 23L Capacity】 This cooler backpack offers 23 liters of space, fitting 36-40 standard 355ml cans – enough for a family of 4-6 on a picnic, or a full day's supply for a hiking backpack adventure. It also works great as a fishing backpack – keep your catch and drinks cold for hours. The smooth double zipper opens wide from either side, making packing and retrieving effortless.
【Smart Multi-Compartment Design Stays Organized】 Stay organized with a thoughtfully designed storage system. The spacious main compartment holds all your drinks, ice, and food containers. The front zipper pocket keeps your phone, keys, or wallet within easy reach. Two deep side mesh pockets are perfect for tall water bottles, or an umbrella. The elastic storage netting secures items on top, preventing shifting while you move. Everything stays in its place – no more digging around.
【Versatile & Comfortable】 Use it as a beer cooler, boat cooler, ice chest, lunch bag, or outdoor backpack for both men and women. The ergonomic padded shoulder straps relieve pressure and fatigue, while the lightweight design ensures all-day comfort – whether you're on a boat, at the beach, or hiking a long trail.
