How to Choose A Beer Koozie – Buying Guide

How_To_Choose__Beer_Koozies

The great thing about beer bottle insulators is that they can be used virtually anywhere because a standard beer can cooler doesn’t require much space to pack. If you choose to take it with you, you’ll be greatly rewarded.

A top rated beer bottle cooler will keep your beer frosty and cold, even in the intense summer heat. But whether you need a or an ordinary beer can cooler or some cool can koozies, be sure to consider the following features if you want the best results.

Size and Fit

The size of the koozie will mostly refer to how snug it fits around your beer can or bottle. The snugger the fit, the better these awesome koozies will do their insulating job.

Always make sure that your unique koozies fit the bottles or cans that you want to put in them. As you’ll see later, some materials (like neoprene) are elastic and can fit various bottle and can sizes.

Design and Extra Features

Thanks to the increase in popularity in recent years, there are a lot of different koozie designs to choose from. You’ll come across a lot of awesome koozies with different styles, colors, and goofy prints. Some unique koozies even come with extra features that make using them more convenient. These features might include a:

  • Bottle opener – placed on the bottom to quickly open bottles.
  • Front zipper – unzip to put a bottle inside and then zip up to cover the whole bottle.
  • Carabiner – attach the koozie to your belt, bag, or backpack.
  • Magnet holder – attach the koozie to any metal surface so the drink doesn’t spill.

Koozie Materials

A large variety of materials is used to make beer bottle insulators, each with its upsides and downsides. Foam, neoprene, and stainless steel are the most commonly used, with the latter two leading the way in terms of efficiency. Depending on the material, beer can coolers can be hard-sided and soft-sided. 

Foam

Foam is a very good insulator, able to keep your beer cold for a long time. Its thickness makes it efficient, but also makes it bulky.

Another downside is that they can tear if a lower-quality foam is used. Still, since they are the most affordable, many people go with foam koozies.

Neoprene

Neoprene is widely known as a material used to make wetsuits. When diving, it keeps the human body insulated against cold water.

However, neoprene does the opposite insulating your drink – rather than keep the cold out, it will keep it in. These cool can koozies are soft, elastic, and very durable. They also save space because of their ability to be squished down for storage.

Stainless Steel

If you want a sleek and stylish design, a stainless steel insulated beer koozie is the best option. Unlike foam and neoprene models, these koozies are hard-sided (meaning they require more space to pack).

Stainless steel may even be the best insulating material, able to maintain the temperature for a long time. Still, many people go with soft-sided models because they are easier to take with you, so it’s a matter of personal preference.

Other Materials

As alternatives to the materials we talked about, aluminum and polyester can also be used to make cool beer cozies. But even with their advantages (lower weight), they won’t be as effective at keeping your beer cold. They also tend to be less durable than neoprene or stainless steel.

Insulation and Efficiency

Regardless of the model and material, good insulation is key. After all, it’s a koozie’s main job. If a beer can cooler or beer bottle insulators aren’t working, they will be of no use to you (unless you like them as decoration).

The insulating layer works by minimizing the heat transfer between the bottle and the air outside. The heat will come from two sources – air (sunlight) and your hands. Cool beer cozies work as a barrier that can keep any type of heat from reaching the beer inside.

Durability

If you want to use your beer can cooler for a long time (obviously), make sure the product you’re getting is durable. It would be a bummer if your koozie broke or wore down after only a few trips.

An insulated beer koozie should survive a few knocks, spills, or tips without being damaged. Metal koozies cannot be torn but are more vulnerable to falls, while a fall won’t damage a neoprene or foam koozie but a sharp object might.

FAQs

Q: Why use a beer koozie?

A: 

You should use a koozie to keep your drink cool on a warm sunny day. It’s a sleeve that goes around the can or bottle and insulates it. As a bonus, a unique koozie can also help you recognize your drink at a party. Our beer koozie reviews will help you find a model that you’ll enjoy taking with you anywhere.

Q: How does insulation work in beer koozies?

A: 

A beer bottle insulator comes with an insulating layer that prevents outside heat from reaching the can (or bottle). By blocking heat transfer, it allows the cold drink to keep its temperature. Depending on the material, different koozie models are more or less efficient at doing this. 

Q: How to wash a beer koozie?

A: 

This depends on the materials your koozie is made of. For example, soft-sided koozies (neoprene, foam) are usually hand-washed or spot-cleaned with mild detergent and warm water. Hard-sided koozies are usually washed like regular dishes.

If you have unique koozies with extra features, make sure to follow the manufacturer’s instructions about care and maintenance. And, regardless of the type and how you clean it, make sure that your koozie is 100% dry before storage to prevent mold, rot, or mildew.

Q: What are koozies made of?

A: 

Koozies are usually made of foam, neoprene, or stainless steel. Foam is efficient and cheap, but bulky and less durable. Neoprene is soft and works well, but costs more than foam. Steel also does a great job, but it can’t be folded and packed. If you want to learn more, check out the materials section in the buying guide above.
