Not warm enough
Used this on a recent trip to Utah, with low temps in the mid-upper 40's. Woke up cold both nights in long layers, and had to double up. Held to the light, you can see there is barely any down. I'd rate it as more like a 50 degree bag.
Bought this quilt as a summer quilt for backpacking, as the weight savings and pack-ability are awesome, but it has been doing great so far in the shoulder season. I have had it out twice so far, once at Sparks Lake in Bend, OR, and once on a two night backpacking trip up in the Steens Mountains. It performed extremely well both times. Straps did a great job of keeping the quilt stationary while I spun around looking for a comfortable position, due to a need for a new sleeping pad.
I was able to push it's temperature limits on both trips where the temps dropped into the mid 30's and it worked very well paired with the ghost whisperer down jacket. Excited to test it out on some warmer nights with the footbox open. The material is super comfortable, and the design appears rugged. Would recommend.
