How to choose jumbo insulated cooler bags?

1. Choose the right size

Make sure you choose the size that suits the number of items you load. Because if there is a lot of space left inside, the effect of jumbo insulated cooler bags may not be so good.

If you need a food or drink box for 1-2 people, the ideal size is about 5 liters compact. The 15 liter medium is more versatile and can be used as an additional cooler for cool outdoor picnics, sports events or shopping.

If you want to use it outdoors (e.g. camping), we recommend choosing a maximum of 30 liters to keep cool for a long time. Just put it into the cold storage bag or empty frozen water bottle to improve the cold storage efficiency, keep your fresh food, vegetables or fruits, and keep them fresh, delicious and lasting longer.

However, jumbo insulated cooler bags are soft and thin. If they are too large, they will be inconvenient and not durable. Therefore, please choose according to your actual needs.


2. Choose convenient zipper products

In order to use the jumbo insulated cooler bags comfortably and stably, the opening and closing method of the bag is also very important. If you are exposed to real products, we suggest you choose a zipper jumbo insulated cooler bag that can be opened and closed smoothly.


3. Choose a jumbo insulated cooler bag that is easy to clean

Because its jumbo insulated cooler bag always needs to be used in clean conditions, please choose products that are easy to clean and use materials that are easy to remove.


4. Choose a jumbo insulated cooler bag that will not deform and is highly durable

It is also important to choose portable products that will not deform, and how easy it is to carry when checking heavy items. It is recommended to check whether it can be held with both hands. And adjust the style of shoulder straps so that they won't be pressed on your shoulders, imagine what it would look like if you actually use it, and choose the product that is most suitable for your own use.


Since shoulder straps and bags are load-bearing parts, it should be checked whether the reinforcement stitches are firm, and it should also be based on user comments.


5. Check refrigeration performance by material and thickness

The efficiency of jumbo insulated cooler bags varies according to the materials used. Although the same insulation is used, the performance will also vary according to the thickness. Therefore, let's first understand the characteristics of each material and select the products with appropriate thickness.

Aluminum foil insulation: it will keep cool when used with other insulation.


Aluminum insulation has the property of helping to reflect heat. It can be used in combination with other insulators (not just aluminum insulators) to improve the efficiency inside and outside the bag. In particular, the external insulator can prevent sunlight radiation and improve the refrigeration efficiency.

PVC tarpaulin: good waterproof, easy to clean dirt and low price.

PVC tarpaulin is a heat-insulating fabric treated with PVC. PVC is characterized by good water resistance, easy to clean dirt, and keep cool compared with other materials. Most products are not too expensive. It can be said that it is the most qualified and reasonable material in the thermal insulation bag.

Polyester or PE foam: thicker and cooler.

Polyester or PE foam is a thermal insulation material that blocks the air. But there are disadvantages: the price will be higher.

Polyethylene: cheap, waterproof and cooler.

Polyethylene is a good waterproof insulator and cheap, and because water is difficult to leak out, you can pour water or ice into it and then cool drinks, desserts or fruits.
