What’s the Most Overlooked Prep in Your Opinion?

Water purification backups always seem to get ignored. Everybody stores water, but what if your main filter system fails or gets lost? Curious what other “backup to the backup” items folks have that don’t get enough attention.

Something I think hardly anyone talks about is backup ways to start a fire. Matches and lighters are great until they’re wet—or empty. Old school flint and steel or even a magnifying glass are so easy to toss in with your gear, but I don’t see them mentioned much. Anyone else worry about this or am I just overly cautious?
