What’s the One Prep Item You Never Leave Behind?

[TeaTimeTalisman]

If you had to grab just one item from your bug out kit in an emergency, what would it be? For me, it's always my multi-tool—can’t beat the versatility. Curious what tops everyone else's must-have list and why.

Water filter, hands down. I’ve tried going without in the past (just for practice!) and realized nothing else matters if you can’t trust your water. Even a tiny Sawyer or Lifestraw takes up almost no space and saves so much hassle. Curious if anyone here has actually had to use theirs in a pinch?
