There’s no reason to get fancy with a first aid kit, a ziploc bag kit works just fine and, like the author says, has some advantages too.
Regarding the contents, I’d say he has the basics covered though I may have tossed in a few more OTC meds, such as Benadryl and perhaps something like Diotame (for things like diarrhea, nausea, indigestion) since they take up very little space. A pair of non-latex gloves would be good to include as well and also take up minimal space.
The beauty of a quick “grab and go” first aid kit like this is that it can be easily tailored to your specific situation, so if you need to include something more specific like prescription meds then you can do that no problem and then just remove them at the end of the day…
“I keep a ‘do-it-yourself’ First Aid Kit in a quart size Ziploc bag to fit nicely into any number of my various ‘bags’ (backpack, my Versipack’s, etc..).
Why do I do keep a First Aid Kit in a Ziploc?
While I do have a few other more substantial First Aid Kits, the minimalist (Ziploc) First Aid Kit works well for me because I can just slide it into a small space in my pack. Even if the pack is full, there’s a way to get it in there… Actually I just leave these Ziploc kits in the various bags so they’re always there.
There’s no extra bulk or weight of a hard container and there is the advantage of being able to see right into the Ziploc and what’s inside.
