Altair is the twelfth brightest star in the night sky, and is used in celestial navigation.

• Two flexible fabric bands keep your bag centered on your mattress and eliminate problems with sliding, twisting and cold spots. SynergyLink™ Connectors fit any mattress up to 25 inches (63 cm) wide.
• The Altair features three-dimensional baffled insulation on the top and sides, and sewn-through insulation on the bottom that partners with your mattress. 85% of loft is placed in the top of the bag, while 15% is placed in the bottom.
• Therm-a-Rest sleeping bags are designed with extra room in the torso to allow your shoulders, elbows and hips to move freely. At the head and foot the fit is closer, keeping you warm while decreasing overall weight.
• Lightweight 750+ fill goose down insulation provides optimal warmth and compressibility. A 30D ripstop nylon shell offers lightweight performance and durable water-repellant (DWR) protection.
