Turns out hers was a Megan Racing "universal" oil catch can --

I have an RX Catch Can myself, and my car sits outside in the driveway year round since my garage is full of my other two cars so I'm surprised I haven't had the same problem.
I'm guessing the oil level tube that's outside of the oil catch can is what is really susceptible to the cold air.
We live in metro Detroit so it's not as cold as some other states, but it's definitely been one of the coldest winters we've had.
What would you guys recommend for cold climates? Are there any that are better "insulated" than others? I was thinking the powdercoating on my RX catch can might help insulate it a little better? Or is the RX Catch can only painted?
