Collapsible koozies are a great invention. They help keep your drinks cool while being small enough to carry around anywhere. Unfortunately, the human memory isn’t always so great. People often leave their custom coozies at home and then don’t have them when they want them. The best way to prevent this problem is to keep a bunch of koozies in the places where they’ll be most useful to you.

Here are three places where you should put a coozie so that you’re never without one when you want it:

1. Your car. Chances are that if you’re going to be going somewhere, you’re going there in your car. Since that’s the case, keeping a coozie or two in the trunk can help to guarantee that you’ve always got one handy.
2. Your travel bag. There are going to be times when you aren’t actually in your car but are somewhere else in the country. Travel is a time we frequently forget our conveniences so packing a koozie in your travel bag before you even go on a trip can make it easier to have one handy. Travel’s a great time to have a cold drink, too!
3. Your day bag. In addition to your travel bag, you probably have a bag that you carry around on a more regular basis. Whether it’s a purse, a laptop bag or a gym bag, it can hold a koozie without much problem.

You can just buy cold drinks wherever you go but then you’ll have a collection of stadium cups and plastic bottles to contend with. Carry around koozies to keep things simpler.
