This an amazing sleeping bag. I used a Marmot Trestles 15 degree F. bag for a while and it sucked in every way compared to this bag. The 30 degree Wicked Fast was head and shoulders warmer than the Trestles. It is ten times lighter, packs to the size of a large grapefruit, and performs flawlessly.
I have had this bag in 10 degree weather and I was fine. I was in a tent and I was using a bag liner from REI to add 15 degrees warm to it and I had to take the liner out from over heating. I was hot! As soon as I took out the liner the bag was perfect in 10 degree weather!!
My only concern was I could see a couple of feathers sticking out when I got the bag and I simply plucked them out and now it is fine. I used this bag in 40 degree weather as well and it was warm but I just opened the foot vent and let down the zipper and I was fine as well. This bag is freaking great!
