The new down sleeping bags will help you sleep well! They are a bluesign® product and ensure a worry-free night's rest through environmentally friendly manufacturing, fair production conditions, and the use of certified down according to the RDS (Responsible Down Standard). But that's not all! Trapezoidal chambers prevent the filling from shifting, thereby eliminating cold spots. Despite its high loft, the Astro has a small pack size, making it suitable for those who want to keep their luggage lightweight.
