I still have this half bag for sale. Willing to take $80.
I've been thinking about how to answer the question of "how warm." Really hard to say for sure. Depends on so many factors- whether using a jacket or not, humidity, wind speed, what was for dinner, how much your outer bag might compress this bag. All I can say is it will make your legs warmer than they would have been otherwise. I would take this along when temps were expected to drop below my bag's rating, and add a down or synthetic jacket as well.
