Alps Mountaineering has introduced a one-and-done sleeping-bag system that meets the needs of multi-climate campers. The new Aura System offers three different configurations to keep campers comfortable in everything from cold to warm-weather climates.

The Aura System is based on a 30°F mummy bag featuring a two-layer offset construction which promises to eliminate cold spots. Quilted between the polyester liner and nylon ripstop outer layer is TechLoft Micro insulation, which delivers the base 30°F rating. Insulated chest and zipper baffling further combat cold-air intrusion for a comfortable night’s sleep.

When temperatures take a dive, the Aura System can be converted to a 15°F mummy bag by installing the quilt top with enclosed foot box. This adds an additional layer of heat-trapping insulation to the bag and foot box. Simply slip the quilt’s foot box over the base bag and secure the quilt to the bag via dual #8 zippers and hook-and-loop patches along the chest baffle.

An incidental feature of this system is the space created between the bag and quilt. If even more warmth is desired, the camper can insert clothing between the layers. It’s also a great solution for dressing on cold mornings, because clothing stays warm while layered in the bag. The quilt can be removed to reduce weight and bulk when backpacking in warmer temperatures.

Finally, the Aura System’s removable quilt works great as a standalone during warm-weather camping. It is perfect anytime a light wrap is needed, such as when sitting around a fire on a cold night, or when sleeping in a hammock.
