The Astro SQ is a new addition to the Astro line. This down sleeping bag features a straight cut for plenty of legroom and a special zipper for easily joining two sleeping bags. The all-around zipper also lets you use the sleeping bag as a large blanket. The Astro SQ is also a bluesign(R) product, meaning that it is made sustainably, under fair production conditions and to minimize the impact on humans and the environment. We also exclusively use RDS down (Responsible Down Standard).
