Do I actually need an RFID-blocking passport wallet?

Across the reviewers we read, RFID blocking is treated as a low-cost nice-to-have rather than a critical security feature - modern e-passports already have shielding built into the cover, and documented skimming attacks on passports in the wild are rare. Most picks in this category include RFID-blocking fabric by default, so it's rarely worth paying extra for, but also not a reason to avoid a wallet you otherwise like.
