Travis Wattswrote a review of The North Face Aleutian 3S Bx Sleeping Bag: 20 Degree on April 3, 2013
I got this bag about a month ago and have used it once in 30-degree weather. Combined with a sleeping pad it kept me warm throughout the night. This is my first mummy bag and I have to say they do take a little getting used to. But the Aleutian 3S is a good transition into the mummy bag camp.
Comfortable, warm, and affordable-the trifecta I need for a good camping trip.
