I'm not going to re-hash my old thread comments about lighters, but I really can recommend this insert for Zippo lighters. Personal experience in all weather, and with the insert soaked and blown dry. Experience from 5+ of my outdoorsman-friends in similar. Experience from one hunting buddy who also runs a pipe shop and sells/repairs a wide range of lighters.
---we all stow a few bic lighters for backup. But this insert is our first go-to lighter. Has not failed under any circumstance in which any other lighter worked.

Retail cost is around $12-$13. LARGE fuel tank holds and retains a lot of fuel..even when stored. We never use Ronson fuel, but any other butane worked well. Fits in the larger, not smaller, Zippo case.
