This is the field-proven, feature-packed down bag you've always wanted. Therm-a-Rest loaded this bag with the comfort features that Therm-a-Rest bags are known for. Their SynergyLink™ Connectors integrate the bag with your sleeping pad while allowing the Zoned Insulation to keep fill where you need it most. The fit of the bag has been perfected in Therm-a-Rest's onsite cold chamber to create their W.A.R.M. fit that allows room for multiple sleep positions without compromising thermal efficiency. Stuffed with water-resistant 650 fill Nikwax Hydrophobic Down certified by the Responsible Down Standard, the four-season Questar is ready for your next backcountry adventure. The Questar is offered in three sizes, and designed to fit both men and women. Compression sack and storage sack included.


  •  650-fill-power Nikwax Hydrophobic Down absorbs 90% less water and dries 3 times faster without using dangerous PFCs

  •  Zoned down insulation maximizes warmth and saves weight by intentionally placing fill where you need it most
