Fill: 725 Fill
Temperature Rating: 24F - 5F
Weight: 1lb 13oz
Price Paid: $300
I've had this bag for about six months now. I've had it in temperatures ranging from approximately 60F - 28F. At the lower extreme, I was plenty warm wearing a T-shirt and mid-weight Marmot long underwear pants. The only exception was that my feet got cold (had on one pair of wool socks) at various points through the night.
It is by far the most comfortable bag I've ever owned and definitely the warmest. Judging by how well it performed at 28F, my guess is that it would definitely hold up into the high teens wearing minimal clothing and probably close to the high single digits wearing a down jacket and fleece pants.
If you sleep in this bag for one night, you will never go back to a "normal" sleeping bag -- the super stretch system is unbelievably comfortable. I can sit indian-style in my bag when I wake up without the bag coming off or constricting my legs or head. This is an absolutely amazing bag!
I would also like to add that I have had water get on my bag and have not seen any damage due to that happening. It must have leaked out of my CamelBak in my pack and it did get the hood pretty wet. I have seen no bunching or clumping of down since that point. When I saw it had gotten wet, I simply massaged the down in and around the hood area to make sure there were no clumps -- that probably prevented the damage.
The shell itself is semi-water repellent but I have seen better. That would be a suggestion of mine to the manufacturer -- to improve the water repellency of the shell. The shell itself is very light and is almost transparent. I have no rips and tears in mine but I baby it. Just thought I'd add that.
