Hulongo 30L Cooler Backpack – 35-Can Insulated Backpack for Beach & Picnic

The Hulongo 30L cooler backpack is a mid-range insulated backpack designed for casual outdoor activities. It features 8mm foam insulation rated to keep contents cold for up to 12 hours, with a PEVA silver seal liner and seamless hot-pressed construction for leak resistance. The backpack holds approximately 35 cans (330ml) or equivalent volume at 17.7" × 12.2" × 7.9" dimensions, weighing just 1.2kg empty.

Key features include:

• High-density nylon exterior with PU coating (100% waterproof, scratch-resistant)
• Two insulated compartments for drinks and dry storage
• Multiple pockets (front, side) for accessories
• Padded adjustable straps for comfort
• Included bottle opener
• Horizontal zippered design for anti-leak reinforcement

Best for beach trips, picnics, fishing, camping, and light hiking where 12-hour cooling and hands-free portability matter more than premium ice retention or ultra-durability. The lightweight design and reasonable price point appeal to budget-conscious outdoor enthusiasts, though the brand has minimal reputation outside Amazon reviews.
