This bag has been well cared for. Never getting wet and always stored in the storage bag when not in use. Probably slept in a total of 20 nights. It is 600fill and though it does not say on the bag, I believe this is the early 15 degree version as I have comfortably slept in temperatures in the low teens. It weighs just under 3 pounds and has a compression sack to get it into a small volume.
Let me know if you have any questions.
