Overview

For the adventure-minded camper who wants warmth without excess weight, the Therm-a-Rest Questar 32F/0C delivers a thoughtful blend of plush comfort and rugged practicality. This lightweight mummy bag is designed to perform across three seasons, with a compact footprint that fits well in a backpack without sacrificing sleep quality.

Core technologies and warmth

• 650 fill Nikwax Hydrophobic Down that absorbs significantly less moisture and dries faster, helping you stay warm even after a damp night.
• Down processed without PFCs, preserving loft while supporting quicker drying after wet or humid conditions.
• SynergyLink Connectors help pair the bag with a compatible sleeping pad, promoting consistent comfort and reducing heat loss at the bag–pad interface.
• Zoned Insulation concentrates warmth where you need it most, delivering a balanced thermal feel without unnecessary bulk.

Design and construction

The Questar 32F/0C features a traditional mummy silhouette with a cinchable hood and an insulated toe pocket. A left-side zipper, combined with a draft tube and draft collar, works to minimize cold drafts. The outer fabric uses 20D ripstop polyester with a durable water-repellent finish to resist light rain and mist while keeping weight down. Designed to fit both men and women, it is offered in Small, Regular, and Long to accommodate different heights and sleeping styles.
