I found that a fanny pack is large enough to carry the essentials but small enough that I will wear it. Mine is 4" x 6" x 9" and is black. Simple thing I picked up a Target for about $12. I keep it in the glove box of my vehicle. Easy to wear during family outings to the park, festivals, hikes. <br><br>I would say the duct tape, band-aids, and knife are the mostly frequently used items.<br><br>
