You don’t need to spend hundreds on a bug out bag. With the right prioritization, you can build a solid 72-hour emergency kit for under $50 that fits in any closet. If you work across town, you might also want a lighter Get Home Bag for your commute.
The Philosophy: Needs Over Wants
Most prepping guides overload you with “nice to have” gadgets. But in a 72-hour urban emergency, you only need four things: water access, food, warmth, and light. For water access, grab one of the filters from our Sawyer Mini vs LifeStraw review.
