I bang out long hours (up to 12) and long miles (up to 35), which makes getting a good night’s sleep critical—so I can get up and do it again the next day. This 800-fill down heater is the first quilt-style bag I’ve used that hasn’t left me shivering.
With 3.5 inches of loft and an extra-wide torso area (which facilitates a good seal), the Sniveller kept me warm down to the high teens when paired with my Therm-a-Rest Z-Lite. The combination of Velcro, drawstrings, and loops let me cinch it down tight around my pad to keep out gusts on Mt. Hood.
And the DWR-treated, 30-denier nylon shell fended off heavy dew and splatter that came in under my tarp. It worked great in warmer temps, too; just drape it like a loose blanket for more airflow. $325; 2 lbs. (reg.); 2 sizes; jacksrbetter.com.
