Frequently asked questions about Cooler backpacks

How does a cooling backpack work?

A Cooler Backpack uses an insulating inner lining that minimizes temperature differences. Combined with ice packs, the contents stay cold or warm for many hours. The tight construction prevents heat from entering or cold from escaping.

How long does a cooling backpack keep cold?

In general, you can say that for short trips, like day trips, many Cooler Backpacks with enough ice packs can easily keep the contents cool for several hours. For longer, multi-day tours, a Cooler Backpack with especially good insulation and powerful ice packs is recommended. That’s why we recommend our Petromax Cooler Backpack, as it keeps your drinks and food cold for up to 8 days. This way, you can easily set off on long hiking tours!

How do I pack a Cooler Backpack properly?

Heavy items go on the bottom, delicate foods on top. Ice packs should be evenly distributed, and the food should be pre-chilled. The less often you open the backpack, the longer the contents stay cold.

How do I properly clean a Cooler Backpack?

After each use, it’s best to give it a thorough cleaning with a mild detergent and warm water. Make sure the main compartment is completely dry before storing the backpack again. Avoid harsh cleaners to protect the waterproof coating.

How do I store the Cooler Backpack?

Best kept dry, open, and protected from light. This way, the material stays supple and odorless – ready for the next Adventure.

What should you look for when buying a cooling backpack?

A good cooling backpack impresses with a combination of insulation performance, material quality, and carrying comfort. If you want to keep food and drinks cool for hours, you should pay particular attention to the construction and workmanship.

The following points are decisive:

  • Insulation performance and cooling capacity:
    The most important property of a cooling backpack is its ability to store cold or heat for hours. High-quality insulation prevents temperature fluctuations and ensures that food stays fresh even on hot days. Models with a dense inner coating and reinforced zipper keep the temperature particularly constant.
  • Material and workmanship:
    Only robust, tear-resistant materials guarantee longevity. On the outside, hard-wearing fabric provides protection, while on the inside, a waterproof coating keeps moisture back – so the contents remain safe, even if the backpack is standing in wet grass. Reinforced seams, stable zippers, and leak-proof designs prevent liquids from escaping.
  • Carrying comfort and construction:
    A well-thought-out design with a padded back section, adjustable shoulder straps, and side pockets makes the backpack comfortable to carry – even when fully loaded. A clear layout with a large main compartment and additional compartments for cutlery or ice packs ensures order and easy handling.

A Petromax Cooling Backpack meets all these criteria: stable, functional, and reliable – for every adventure.

What size should a cooling backpack be?

The right size depends on the intended use. Whether it's a day trip, weekend trip, or multi-day camping – the liter volume determines how comfortable you are on the go.

  • Small models (10–12 liters):
    Ideal for solo adventures or short hikes. They offer space for drinks, snacks, and a small meal.
  • Medium models (15–20 liters):
    Perfect for couples or day trips. Several bottles, supplies, and accessories fit in here – without unnecessary weight.
  • Large models (from 25 liters):
    The best choice for families, groups, or longer camping trips. They offer sufficient storage space for several meals and drinks.

When camping with two people, 18 to 20 liters are usually sufficient. For longer trips or larger groups, a model with more volume is worthwhile – so everything remains cool, clear, and easy to transport.
