Questions

Why does a 20F-named Parsec show an 18°F lower limit?
The model name is nominal; Therm-a-Rest lists 29°F comfort and 18°F lower limit. Those are distinct figures, and neither is a personal warmth guarantee.
Can I add a quilt to Parsec 20F for a colder trip?
Yes. The bag has quilt and blanket loops so you can layer a quilt or tech blanket for more warmth. Alone it is rated EN Comfort 29 °F (-1 °C) and EN Limit 18 °F (-8 °C); Therm-a-Rest gives no combined rating for a layered setup.
