We sleep easy in the frigid backcountry with the Therm-a-Rest Questar Sleeping Bag. The zoned hydrophobic down gives us added wet-weather warmth where we need it most, while the box baffle construction maximizes loft and minimizes cold spots for cozy Zs all night long. No matter how we shift and sleep, the roomy mummy shape lets us do so freely and comfortably, while the removable SynergyLink Connectors ensure we stay atop our sleeping pad.
