Description
Custom Logo Wholesale Waterproof Cooler Backpack – 20L Insulated Beer Bottle Bag
The short answer for sourcing teams: the JUNYUAN Waterproof Cooler Backpack is a hands-free insulated backpack that carries 20+ liters — about 24 beer bottles (330 ml) or 20–36 cans with ice — and holds temperature below 4°C for 24+ hours (up to 48 hours in optimized conditions) behind 40 mm insulated walls. The 600D tear-resistant exterior, welded seams and airtight zipper make it leak-proof, while padded straps keep it comfortable for hiking, beach days, tailgating and promotional programs. It is built as a private-label model in our SGS-audited Quanzhou factory, MOQ 500 pieces.
Backpack coolers have become the fastest-growing soft-cooler format for outdoor brands because they leave hands free for gear; the category is commonly benchmarked by can capacity and ice-retention hours. Independent insulation guidance, such as the U.S. Department of Energy insulation guidance, shows that thicker closed-cell foam directly improves thermal resistance — the reason our backpack uses 40 mm walls rather than thin single-layer lining.
