How to make a first aid kit for camping
Make a decision about size.
The size of a first aid kit depends on how it is being used, and how many people will use it. In general, if your fist aid is coming with you on a camping excursion it should be big enough to stock adequate supplies for everyone in attendance but also lightweight and portable.
If you're backpacking alone or with one or two other people, keep it on the smaller side as the less items in your backpack the better. Added weight can cause back strain and fatigue that can interfere with your journey.
