Therm-a-Rest’s Questar 20 is one of the brand’s most popular sleeping bags and customers have continually asked for a four-season version. So for Spring 2018, Therm-a-Rest answered the call and will introduce a zero-degree bag to the Questar lineup.
The Questar 0F/-18C offers a cozy night’s sleep in frigid winter temperatures thanks to the 650-fill Nikwax Hydrophobic Down insulation and seams that trap your body heat and radiate it back at you to retain warmth — no cold spots here. The insulation is zoned to give you more warmth where you need it (i.e., not underneath you) while cutting down on excess weight. You also get a Toe-asis Foot Warmer Pocket at the base of the bag to quickly warm up cold toes.
Similar to other Therm-a-Rest sleeping bags, the Questar 0F uses SynergyLink Connectors beneath the bag to slide over your mattress so you don’t fall off in the middle of the night. It also has quilt and blanket loops if you want to layer up with extra down quilts in really cold temps.
The Questar 0F comes in three sizes — Small, Regular, and Long. The Regular size weighs in at just three pounds and packs down to a 10.3-liter size.
The Therm-a-Rest Questar 0F four-season sleeping bag retails for $329.95 and as it is a Spring 2018 product, will most likely start shipping within the next month or so.
