PARTI FISH Insulated Soft Cooler Box, 5-Layer Insulation, Strong Insulation, Lunch Bag, Large Capacity 15L-18L, Expandable, Foldable, Waterproof, Leak

Durable Design with High-Quality Materials: This lunch bag features a high-grade 5-layer construction. The exterior is made of 900D+PU high-density Oxford fabric, combined with an internal PVC layer for a robust construction that resists deformation and offers superior waterproofing compared to 600D/300D materials. A custom aluminum film is incorporated using seamless hot-press technology for complete leak protection.

Large Capacity & Wet/Dry Separation Design: It combines a 1L hidden compartment (for everyday items) when folded and a 5L hidden compartment (for food storage) when unfolded, with a 12.5L main compartment (for food storage). The double-deck structure separates wet and dry items, and the capacity can be freely adjusted with a zipper.

Professional-Grade Insulation Performance: The 5-layer material (900D Oxford/PU layer/6mm EPE insulation foam/non-woven fabric/impact-resistant aluminum lining) blocks heat conduction. The sealed zipper thoroughly prevents heat loss and dust, maintaining food temperature and freshness for extended periods.

Durable for Heavy Use: Wide handles and shoulder straps, high-density stitching distribute load effectively. Featuring a 3mm PE reinforcement plate and non-slip rubber bottom, this bag prevents deformation and damage even with heavy loads. It achieves 200% greater load capacity compared to conventional products.

Multifunctional storage system: In addition to the main insulated compartment, it includes a hidden top pocket (for camera/wallet, etc.), side drink holders, and rear tactical webbing (for outdoor equipment storage). It also comes with straps for securing it to a suitcase for stability during travel.
