Description

Corus 20F offers an open quilt format with a footbox and neck snap instead of a fully enclosed hooded bag. Its 32°F comfort figure keeps the warmer-season role separate from its 20°F lower limit.

Questions

How does the Corus footbox help manage drafts?
It can fit over the pad or over the sleeper's feet, while the neck snap helps hold the quilt in place. Ground insulation and careful edge placement remain part of the sleep system.
Which sleeping pads work with the Corus 20F SynergyLink straps?
Therm-a-Rest says the removable SynergyLink connectors work best with regular-sized pads that are 3 inches thick or less when inflated. They secure the quilt to the pad; the quilt itself is rated EN Comfort 32 °F (0 °C) and EN Limit 20 °F (-6 °C).
