Deuter's new down sleeping bags make sure you sleep well! They are 100% bluesign products and let you rest assured thanks to environmentally friendly production, fair manufacturing conditions and the use of RDS-certified down (RDS = Responsible Down Standard).
But that's not all! Trapezoidal chambers prevent the filling from sliding around and therefore the formation of cold spots.
The Astro 550 is ideal for temperatures between -5 to -22°C
