The Thermarest Corus 20F/-6C is a versatile, high performing camping quilt that saves weight and boosts comfort on backcountry adventures.
With even more down loft to keep the colder backcountry conditions at bay, the Thermarest Corus 20F/-6C provides the perfect balance of functionality and warmth that 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.

I'm a larger fella 6'2" and 19 stone. Can't get on with mummy bags and seems the traditional envelope bags with a good r value are bigger packed than my tent lol anyway used with a r7 rated mat I was more than warm enough at about 0°C in 3/4 season tent I toss and turn a lot but with the straps under my mat the quilt stayed put and performed flawlessly
