Save weight and boost comfort when you venture into the backcountry with this high-performance backpacking quilt, the Therm-a-Rest Corus 20 quilt.


  • 650-fill-power Nikwax® Hydrophobic Down™ absorbs 90% less water and dries 3 times faster than regular down without using dangerous PFCs
  • Shell fabric also has a durable water repellent (DWR) treatment to help moisture bead up on the surface
  • Compact and designed to easily fit into your pack
  • Box baffled construction uses mesh walls to maximize down loft and minimize cold spots
  • Removable SynergyLink™ connectors integrate the quilt with a sleeping pad (not included) for optimal efficiency and comfort
  • Precisely shaped footbox can slip over your pad to eliminate drafts or over your feet for extra warmth
  • Full-perimeter side baffles and snap neck closure keep out unwanted drafts
  • Pair with another Therm-a-Rest quilt, sleeping bag, blanket or sheet (not included) to build a layered system
  • 650-fill-power down certified to the Responsible Down Standard (RDS)
  • RDS certification ensures the down does not come from animals that have been subject to any unnecessary harm, such as force-feeding or live-plucking
  • Stuff sack and storage sack included
  • For comfort, use in temperatures down to 32°F; recommended lower limit is 20°F, but everyone's body and sleep comfort differ, so these are simply guidelines
