For 2-season camping Jacks R Better Serria Stealth quilt - 40F, 18oz, 800 dri-down. Has a Velcro head hole so also services as a wearable down poncho for the chilly evenings/mornings at camp. +2oz for a down hood (poncho and sleeping modes). For the third season, I pair/layer it with an equal weight/rated Montbell Down Hugger #5... together good into the 20s (backpacking).
