So... what exactly do Scandinavians do to protect their clothes from moth larvae? I can tell you from sad experience that cedar only kind-of works (I was pretty sad that fall).

I've been giving thought to using airtight tubs - and flooding them with nitrogen. Overkill?

If there's some kind of gadget, guaranteed it was invented by a Swede :-)

Oh, wool trivia: did you know that it's also nearly as fireproof as Nomex? Back in the 90s, one of the F1 drivers (from NZ, unsurprisingly) drove with a woolen fireproof suit.
