Frequently Asked questions
Is this sleeping bag warm enough for cool-weather camping or travel?
Yes, this sleeping bag is great for cool-weather camping, especially the Flame 15°F or 25°F sleeping bag models. The 15°F will get you to early winter temperatures when paired with an insulated sleeping pad (3.5 R-Value or higher).
Can this sleeping bag be used as a liner in another sleeping bag?
Yes. You could use the Flame 55°F or Flame 48°F sleeping bags inside another bag to boost the thermal performance for cold-weather use. Tip: add one of these to a 20°F sleeping bag instead of buying a 0°F sleeping bag for occasional winter use.
Can this sleeping bag be zipped to another sleeping bag?
No, this sleeping back does not join with another. Even though the 25°F and 15°F bags have full-length side zippers, they're not designed to be coupled.
