Omnipod/Dexcom in freezing weather

Hello T1D fam,

I’m about to travel to Finland soon and need advice on how to handle devices as I don’t have experience with freezing cold weather (I live in sunny California). The temperatures are gonna be -4F and I have no idea if the insulin in my Omnipod is gonna freeze or not. What about Dexcom G7? Will it stop working? Looking for any advice on how to deal.

Thanks!
