Idk about jet lighters like that, but even Bics have a hard time lighting when they are below freezing so I can't imagine the jets would burn very strong (if at all). You would need to keep the thng in your asscrack in cold weather. Plus a lot of those cheap ones leak and burn fuel really fast so I hope you bring an extra can of butane.
