The North Face Inferno Sleeping Bag

Yes, it is designed for alpine environments with a 15°F temperature rating. The 800-fill ProDown and aluminized XReflex treatment provide significant warmth for cold-weather backpacking and mountaineering.

These areas are prone to condensation buildup when your breath or body heat hits the cold fabric. The waterproof material prevents moisture from soaking into the down insulation, which keeps you dry and maintains the loft of the bag throughout the night.

The Inferno uses trapezoidal baffles, which are specifically engineered to keep the down insulation evenly distributed. This design minimizes shifting and prevents the cold spots often found in standard sewn-through construction.

Yes, the bag features rear shock cords designed to secure it to your sleeping pad. This ensures you stay centered on your pad throughout the night and prevents you from rolling off onto the cold ground.

This bag is designed for users up to 72 inches (6 feet) tall. If you are near this height, you may want to consider how much room you prefer for movement, as the mummy shape is designed to be efficient and snug.

Yes, the Inferno uses 800-fill ProDown that is RDS-certified. This certification ensures that the down comes from animals that have not been subjected to unnecessary harm.
