What’s Your Must-Have Item for a 72-Hour Kit?
When putting together a 72-hour kit, I keep going back and forth between a solid water filter and a compact solar charger as my top must-have. I’ve read arguments for both, but space and weight are always a concern. If you had to pick one thing you wouldn’t go without in your kit, what would it be and why? Also, does anyone have experience with the newer mini solar panels—are they worth the space?
