Waterproof Lunch Backpack for Men Women

From the manufacturer: Introducing the upgraded version of our Maelstrom coolers, the cooling backpack with a spacious capacity of 36L. We have incorporated the latest ultrasonic welding technology to ensure leak-proof and heat preservation capabilities. This backpack provides various carrying options, making it the perfect companion for camping, hiking, or beach trips.

Stretchy Straps: Our backpack features elastic straps that securely hold picnic cloths or clothes in place, preventing them from slipping off.

Additional Side Handles: We have included handles on both sides of the ice pack for added convenience and versatility. These handles not only make it easier to carry the cooler bag but also improve its balance and maneuverability.

Lightweight: Unlike traditional plastic coolers that are big and heavy, our ice pack is made of lightweight materials that take up minimal space and can be easily carried around.

DIY Pattern: Personalize your cooler backpack by attaching Velcro flags or other patterns of your choice.

The Maelstrom cooler backpack is made of high-quality nylon material, which is more durable, scratch-resistant, and waterproof compared to ordinary materials. To ensure optimal insulation, we have added five layers of different materials, allowing for a cooling effect that lasts up to 16 hours.

Large Capacity & Insulation & Leak-Proof: With a capacity of 36L, our insulated cooler backpack can hold up to 50 cans. The main pocket is designed to keep food and drinks cool, while the upgraded leak-proof lining prevents any leakage and maintains the temperature for 16 hours.

Multiple Compartments: Our portable cooler features insulated and waterproof compartments for food storage, a main compartment for ice packs and drinks, a front zip pocket for tableware, and two large side pockets and a mesh pocket for wine or water bottles. Additionally, hidden pockets on the back provide storage for your mobile phone and valuables.

Durable & Ergonomic Design: Crafted from heavy-duty nylon, our lunch bag is tear-resistant, scratch-resistant, and lightweight for easy carrying. The adjustable shoulder straps and ergonomic design cater to individuals of different heights, while the shock-absorbing foam back ensures maximum comfort, softness, and breathability.

More Design Highlights: Enjoy the convenience of a bottle opener attached to the shoulder strap for easy access to beer and drinks. The front of the pack features an elastic rope net for holding picnic mats, as well as 10 webbing holes for keys, water bottles, and other tools. The shoulder strap also includes a stretch cord for hanging sunglasses, and the front pocket has a Velcro attachment for personalizing with flags or other icons.

Using Occasions: In addition to being an excellent insulated and leak-proof bag, our cooler backpack is versatile and can be used as a lunch backpack, hiking backpack, camping backpack, fishing backpack, travel backpack, ice chest, and for various outdoor activities such as hunting, cross-country, biking, and more.
