Thermarest says:
The same versatility you love with even more down loft to keep the colder backcountry conditions at bay. Its perfect balance of functionality and warmth make it ideal for three-season backcountry adventures or for layering in colder conditions. Made with high loft, packable Nikwax Hydrophobic Down and Box Baffled construction for retaining heat and excellent temperature regulation, the Corus offers a surprisingly liberating feeling of unrestricted movement throughout the night. The footbox can slip over your pad to eliminate drafts or over your feet for extra warmth.

Our Verdict
The Therm-a-Rest's 2020 Corus 20 Down Quilt, is ideal for those seeking ultralight performance and amazing comfort without a weight penalty. It features a huge amount of 650 fill of responsibly sourced Nikwax Hydrophobic down which vastly improves its performance in damp conditions and takes the Comfort Limit down to an impressive -6°C. The impressive box wall construction for the baffles is something you only get on top quality down products as this technical aspect allows down to loft much more effectively while also reducing heat loss through cold spots along stitch lines.
The spacious footbox fits round the bottom end of your sleeping mat keeping your feet warm and the quilt in place. It also includes poppered snap loops so it can easily be connected to a Thermarest mattress, quilt blanket or sheet allowing you to build a your own sleep system. There is a small pocket at the head end for those essentials you might need to find in a hurry such as a head torch. As you would expect it the pack size is tiny. If you're after a little bit of light-weight luxury on your next adventure then this quilt would be ideal.
