Enigma APEX 30F worked really well for me!
Just did a 4 day backpacking trip through the Eastern Sierra Nevada Mountains, culminating in a summit of Mt. Whitney. First time using a quilt instead of a sleeping bag, and was very happy with the performance of APEX and of the comfort of the "Long/Wide" version of the Enigma. Being 6' 3" and a back & side sleeper, I needed/wanted the extra size and with the straps properly used kept me nice and toasty.
