I've got the same setup. Snagged it on eBay brand new with tags still on all the bags for $50 "buy it now".
Slept outside on the ground in mid December with green and black bags in the bivy and woke up in the middle of the night SOAKED in sweat.
The next night I used just the green bag in the bivy and slept like a baby.
