Hulongo Large Waterproof Insulated Cooler Backpack

What it is

The Hulongo Large Waterproof Insulated Cooler Backpack is designed to keep drinks and food cool on day trips, beach days, picnics, hiking and camping. It combines a sizeable interior with practical pockets, all packaged in a weather-ready, leak-proof backpack.

How it performs on the basics

On paper, the key selling points are straightforward: up to 12 hours of cooling thanks to thickened 8mm foam insulation and a silver PEVA seal, 100% waterproof construction with a PU-coated high-density nylon shell, and a lightweight, more comfortable carry with adjustable padded straps. If you prioritise a hands-free way to transport refreshments and meals without sweating the contents, this model aims to deliver.

What stands out in the design

The backpack features two insulated compartments for separating drinks from food, plus a sizeable front pocket and two side pockets for essentials like snacks, a phone or wallet. A built-in bottle opener adds a touch of practicality. The focus on a seamless hot-press process is marketed to improve leak resistance, complemented by smooth horizontal zippers to further reduce leakage risks.

Capacity and practicality

With dimensions of 17.7'' x 12.2'' x 7.9'' (H x L x W), it promises to hold around 35 cans (330ml) and still accommodate meals or tall beverages. That level of capacity makes it versatile for families or groups, not just solo outings.

Pros and caveats

What you’ll notice day to day: it keeps things cool for a good part of the day, it handles outdoor use (water exposure is a consideration given its waterproof claim), and it’s easier to carry than a traditional hard cooler. It may not be perfect for high-heat, prolonged deep-wilderness trips where more insulation or rugged hardware could be required. Also, the manufacturer offers a replacement or return if a leak occurs, which provides some reassurance when you’re paying for capacity and convenience.

Who it’s for

This backpack suits casual outdoorsy types, beach goers, picnickers, hikers or shoppers who want portable cooling without a dedicated cooler box. It’s well suited to those who value a roomy interior, hands-free transport and straightforward maintenance.

Who it isn’t ideal for

If you need ultra-heavy-duty gear for rugged expeditions or you require extremely long-lasting temperature control in extreme conditions, this model may fall short of that tier. It’s more of a practical, everyday-to-weekend option than a high-end outdoor specialist solution.

What to check before buying

• Confirm the size and weight balance works for your typical use (commuting, walking, or hiking with other gear).
• Consider how often you’ll rely on the leak-proof claim in real-world conditions (spills, rain exposure, uneven surfaces).
• Think about the number and type of pockets you want for organisation beyond drinks and food.

How it compares to other approaches

If you already use a traditional soft cooler or a standard backpack with a small cooler pouch, this Hulongo model offers greater capacity and a dedicated cooling system in a single carry, with the advantage of two insulated compartments. It’s a sensible middle ground between a simple tote cooler and a more feature-rich hard-shell cooler, provided you value portability and straightforward maintenance over peak-long performance.

FAQ

• How long does it keep items cool? Up to 12 hours with the stated insulation and seal.
• Is it truly waterproof? The shell is described as 100% waterproof with PU coating, however, real-world performance will depend on use and conditions.
• What’s included with the pack? The description notes the backpack, compartments, pockets, and a bottle opener, no additional accessories are listed.

Is it worth it?

Worth considering if you want a sizeable, portable cooler backpack with practical organisation and a leak-resistant design for typical day trips and urban outdoor use. It suits most casual needs but may fall short for extreme or technical expedition use.
