An EDC bag is a bag that you carry with you and has the essential items that will provide for your survival needs for a day. EDC stands for "Every Day Carry" bag.
Let's put it this way, as a "prepper" who wants to be prepared for any potential disaster that might occur, you have to realize that this event may occur at any given moment of the day or night.
It is not going to wait until you are at home amidst all your prepper gear. The purpose of the EDC bag is that you will at least have some gear with you at all times. Just enough to ensure you have the essentials until you reach home.
Your needs will vary according to whether you live in an urban situation or a rural one. It will also vary according to your gender and age. Your bag is personally designed for you alone and will be unique.
You have a life and it is important that your EDC bag is not going to be totally out of place in that life, otherwise you will be tempted to leave it in the car instead of taking it with you. If you work and lie in a more formal lifestyle then having an EDC bag that is a military rucksack is going to look odd. You must choose a bag design that blends with your environment.
An EDC bag is NOT the same as a BOB (bug-out-bag). A BOB is designed to cater to your needs in an evacuation scenario and is designed to have the essentials for a minimum of 72 hours.
72 Hours is the recognized norm, but some people try to design the BOB for a week. The BOB would be used if the nature of the emergency was such that you had to evacuate and not stay in your home (which is normally the best option).
The BOB should be ready packed to go at a moment's notice and will be larger than an EDC bag. Some people have the BOB in their car, so it is always available wherever they are. Imagine a scenario where some kind of disaster happens where your home is located and you are the other side of the city. Do you really want to go into the danger zone to collect your BOB?
An EDC is totally different and will contain items that you use on an everyday basis as well as supplementary items in case of emergency. The EDC should be at your side at all times.
There may be a small degree of duplication between the contents of a BOB and an EDC bag, but the EDC bag will also contain a number of everyday items that you use on a normal day.
Your EDC bag is something that you will be carrying around on a daily basis. It should not be so large that it becomes cumbersome to carry around, resulting in you gradually leaving it behind. However, it should not be so small that it does not have space for essential items.
Take this bag seriously, in a real emergency it is going to be your first resource while you collect your BOB (if evacuation is necessary) or while you get home if it is not.
The type of bag you choose will be a personal decision. I get by with a large laptop bag that has a shoulder strap. Ladies may be more comfortable with a large purse, and someone living in the wilds may have no problem with a small rucksack. The choice is yours.
Everybody's EDC bag is going to be different. They are unique to the individual and relate to the lifestyle that they live. However, there are probably ten items that may be common to all bags. We will look at these items next.
I always carry a laptop or tablet with me as a matter of course, and either of these items can be an essential communications tool.
Think carefully about what you use every day in everyday life. There may be items that you already carry that are not on the above list. Paper tissues, headache medication, makeup, I can also think of other items that may be useful in an emergency, like a plastic poncho, a face mask, sunglasses, a small cooling fan (battery). Everyone will have different ideas and that is fine. It is your bag and you decide.
In conclusion remember that your EDC or Every Day Carry is not the same as your BOB or Bug Out Bag. Although you might find some crossover of items your EDC is exactly that, items you carry daily on your person for short term situation or immediate situation but not for Multi day survival.
