How to choose the best insulated backpack?

This section details the important features you should consider before choosing your cooler bag.

 

The type of bag

There are three types of cooler bags on the market: lunch bags, strap-on bags and cooler backpacks.

What to remember about insulated bags?

This type of bag corresponds to small and quite compact formats. To give you an image, these are the traditional lunch bags that can hold a lunch for a day of energy work. Generally speaking, they are removable and offer easy maintenance. You can use them just about anywhere and rely on their straps for easy transport. Further, we love this bag because it targets a wide audience. However, lunch boxes are not the best allies for outdoor activities such as fishing or camping.

What to remember about insulated bags with handles?

These are food boxes that are known for their handles or straps. They are a bit bigger than the previous ones and can keep enough food for at least 4 people. It will therefore be suitable for small cruises or even beach trips. And despite their size, the shoulder bags remain flexible enough to fold and facilitate their storage in an enclosed space.

Moreover, the particularity of this type of bag is the possibility it offers to adjust its shoulder strap. Moreover, the latter is designed with materials that are both flexible and resistant. This way, you will not feel any physical pain when moving your lunch box. However, this is not a good enough reason to carry the bag over a long distance.

What to remember about insulated backpacks?

These are the bags for hikers, campers, fishermen and many other outdoor enthusiasts. Its biggest advantage is the freedom of movement it provides during its use. Their straps are padded with foam to allow your shoulders to breathe while walking.

Next to that, you'll have your hands totally free for other things like holding camping gear or your fishing pole. Finally, the insulated backpack can store more products than the shoulder bag. Better yet, its temperature retention time is also much better.

 

The weight

Always check the weight of the cooler bag before you buy one. Obviously, the cooler comes with an initial weight. Carrying your food and drinks in it will add extra weight. Without this criteria, you will find yourself unable to move your bag.

 

Capacity

The best insulated bag is not necessarily the one with the largest capacity. On the contrary, it is the container that fits the storage needs of its owner. Therefore, the choice of the size of your lunch bag must take into account:

  • The number of people to be supplied;
  • The length of your trip;
  • The distance to your destination.


These factors will help you determine the appropriate size for your needs: between 9 liters and more than 25 liters.

 

Portability

Another important factor is portability. Sturdy side handles will be welcome if you're likely to carry heavy, fully loaded bags on your trip. On the other hand, shoulder straps or slings can be extremely useful for lighter loads, especially if you're carrying other equipment. The goal here is to make your user experience easier in terms of transportation.

 

The compartment

Get insulated bags with optimized compartments. Technically, this can be a main compartment with pockets as reinforcement.

They help a lot if you intend to carry salad, cold cuts or fresh fruit, in addition to drinks. In short, having each type of food in a different space becomes possible in a bag with different compartments.

 

Insulation

Probably the most important criterion is the insulation. The point of having insulated bags is pointless if you choose one that doesn't keep your food items cool or warm.

That being said, check to see if your bag has thermal barriers that help protect your food. Also, pay attention to the number of layers of insulation that the inner walls sport. Of course, it's always better to have more layers. However, you should be aware that thicker insulation will tend to increase the amount of storage space required for your stuff. So it's important to weigh things carefully before you decide.

 

The Cost

Before you spend your money, it is essential to think carefully about how you will use your cooler bag. The type of use you expect from it is also a criterion to consider. It will be more than enough to have a reasonably priced model if you are looking to use the bag occasionally. Pay more for a highly durable model if you need an insulated bag that can withstand extreme outdoor conditions. At Healthy Lunch, all criteria are taken into account to provide you with bags that offer excellent value.

 

How does the cooler bag keep the temperature?

Insulated bags are designed with an inner wall that incorporates layers of insulation. It is these layers that allow it to keep the temperature as long as possible. And to offer a high performance, there are two types of insulation:

  • Closed cell insulation: this is the best insulation system an insulated bag can offer your food with ordered insulating cells.
  • Open cell insulation: this is achieved through polyurethane foam which is a highly insulating material.

 

How to use an insulated bag?

A cooler bag is an investment you need to take seriously. It's not enough to just buy one and put a bunch of food products in it. For best use, you need to know a few key tips:

  • Preheat or pre-cool your food before inserting it into the cooler bag: this is a great way to allow the bag to do its job as a temperature accumulator.
  • Keep the cooler bag out of the sun: sunlight will not enhance the long-term heat retention of your soup. On the contrary, it may alter its quality.
  • Avoid using ice cubes: Ice cubes will tend to melt inside the bag. The sensation of such a result is not always pleasant. On the other hand, you can prefer ice packs.

How long does the insulated bag keep the temperature?

The answer to this question depends on the type of material the bag sports. The more insulating layers the fabric design offers, the longer the preservation. Some manufacturers will make the promise of a 12 hour retention, but admittedly this is not possible. Insulated bags are like flexible coolers and their maximum retention time is 8 hours.

Yes, it is possible to insert ice into the inside pocket of the best insulated lunch bag. The purpose of such action is to extend the shelf life of freshness. However, we recommend ice packs, as they do not melt like ice cubes.

Does the insulated bag retain odors?

It is unlikely that your container will absorb odors from your food due to the quality of their design materials. Likewise, the insulated bag cannot be a haven for mold or bacteria that could lead to unhealthy odors. However, if such situations occur, it is certainly due to a very poor maintenance of the lunch bag.
