Double-layer compartmentalised design with generous capacity, accommodating all your daily essentials in one pack: Featuring a scientifically engineered dual-layer independent compartment system, the main section holds multiple standard lunchboxes while the secondary layer and mesh pockets allow organised storage for fruit, cutlery, beverages or ice packs. This extra-large capacity effortlessly meets food storage demands for family picnics, group camping trips or full-day outdoor adventures. One bag for multiple scenarios, seamlessly transitioning from urban commuting to outdoor exploration: Its sleek, contemporary design serves not only as a professional lunch bag for office workers but also instantly transforms into a food storage solution for camping trips, park picnics, or children's activities. Featuring a detachable shoulder strap, it offers versatile carrying options—handheld, crossbody, or vehicle-mounted—seamlessly bridging work and leisure. Insulation Layer: Features a built-in high-density insulation layer that effectively delays temperature loss. In summer, paired with ice packs, it maintains cooling for 4-6 hours, ensuring drinks stay refreshingly cold and food keeps fresh. In winter, it provides temporary warmth retention, making it a thoughtful companion for safe outdoor dining. User-friendly design elevates experience through thoughtful details: top handle + adjustable, detachable crossbody strap for hands-free convenience; side mesh pocket for quick access to water bottles or umbrellas; waterproof coating and easy-clean fabric lining for effortless wiping; reinforced base and sturdy zippers ensure reliable load-bearing and worry-free use. Robust materials and easy-clean construction combine durability with practicality: the outer layer utilises abrasion-resistant, waterproof oxford cloth or polyester fabric, while the interior features a food-grade, easy-clean lining. Not only does it withstand scratches and scrapes, making it ideal for challenging outdoor environments, but it also allows for effortless removal of grease and water stains, ensuring simple maintenance and long-lasting performance.
