My EDC pack has morphed into my get home bag. It is a Maxpedition Sitka. I just picked up a couple of items that look to be quite promising. They are the Adventure Medical Kits SOL Emergency Shelter Kit and Heavy Duty Emergency Blanket.
I had carried a cheap Coleman emergency blanket. You know those silver Mylar deals. I have used them from time to time over the years and they are one time use at best. I wanted something that was lightweight and would last. So I ordered the above two items. The blanket is much more heavy duty and I think that this setup will serve me well if I need to stay out overnight in an emergency.
If these are items you like to carry I would look into the above mentioned items. They may fit a need for you as well.
