The cat works out of the box: today's soft-surface coolers can be insulated like hard plastic coolers. The best freezer bags are also leak-proof, which means you can find all the benefits of a sturdy hard freezer bag in the bag, which can be easily put away once emptied.

The soft cooler can also be adapted to many uses, and its model is very suitable for a quick lunch break or spending leisurely with the waves. However, before you finalize the deal, here is the information you need to know when buying your next beach cooler, lunch cooler, or even a cheap cooler.

Whether you need them for play or work, the best freezer bags have one main job-to maintain the temperature of the food. The bag achieves this through insulation, leak-proof seams and other functions. Just in time for you to pack your picnic, we have opened a freezer bag for what you need to find.

Insulation is the best cold storage bag's main way to keep food cold or hot, for that matter. Most bags have thermal insulation, which can keep food or beverages at the desired temperature by preventing heat transfer. Think about it: if you put a cup of hot coffee on the counter, the drink will slowly cool to room temperature. But if you put it in a hidden environment, it will transfer its heat to the interior of that space, and at the same time absorb heat from the air around it, until the temperature of the coffee and the hidden space is between the two. between.

The insulation material of the cold storage bag helps to win the heat transfer war, and the best cold storage bag uses foam insulation. The bubbles in the foam and the porous spaces between these bubbles help to slow down the heat transfer. But not all bubbles are the same. Open-cell foam is lighter and more flexible-making it more suitable for soft surface coolers. However, it does not prevent the transfer of heat like closed-cell foam, which does a better job of limiting the interaction between bubbles. Brands such as Yeti have successfully manufactured foam insulation materials that are light and soft enough to hold the bag and bring the best heat dissipation effect to the soft surface cooler. Of course, expect to pay a higher price for technologies that effectively keep the temperature rising (or lowering).  

Seams are essential in soft cold storage bags because they can prevent all kinds of leaks. One type of leak is obvious-if the seams are not tight and your marinated chicken bag overflows, you will clean your luggage and cooler. (Also, if you plan to pour ice into an insulated bag, weak seams may cause the picnic blanket to get wet.)

Although not as confusing, another type of leak may be equally problematic. Remember, they prevent heat transfer by creating a perfectly hidden environment. Leaking seams allow air to flow in and out, thereby damaging the environment.

So what should you look for at the joints of the cooler? The best cold storage bags (that is, the most sealed) are not stitched or glued together, but welded together by heat and pressure. The seal at the top of the bag is also important. Although zippers are the most common and very suitable, Yeti has developed a magnetic seal that is almost as tight as a dry bag. 

The outside of the cold storage bag is important because the material determines the waterproof and other protective measures. The denial of fabric refers to the thickness of each thread. Anything above "1,000 denier" should have sufficient waterproof, mildew and sun protection capabilities. Many bags also use a breathable, element-resistant lining-à la Gore-Tex.  

The capacity of the soft bag is as large as the block hard cooler. However, if you plan to use it as a lunch box instead of a camping refrigerator, it would be foolish to choose a 30-can model. Nevertheless, larger bags can hold more ice cubes, giving you the option to refrigerate food for longer periods of time. In addition, compared with hard freezer bags, the best soft freezer bags have the advantage that they are packable and can usually be folded or rolled up so that they only take up a small amount of space when they are empty.

When your cold storage bag is filled with a case of beer and a bag of ice cubes, you may need extra hands. Models with handles and shoulder straps provide more gripping and lifting methods and more positions. The extra pockets are also useful. Some bags have two insulated pockets so you can put leftovers on top to keep it warm and beer underneath. The front and side pockets are ideal places to store dry goods or keys.

Depending on the cold storage bag you choose, your food can be refrigerated for hours or days. For reference, Coleman's budget package claims that it can keep 30 cans of refrigeration for 24 hours. Of course, the quality of insulation technology is important-Yeti's closed-cell foam, for example, is the leader in Yeti Hopper M30-but size is also important. The larger the bag, the more ice you can hold, so the longer you put ice in the bag, you can keep the food cool.
