Quality synthetic bag
True to temperature rating. Comes with nice stuff sack and compression bag. Certainly not the lightest bag for backpacking, but it's definitely a quality synthetic cold weather bag. No regrets with purchase. Highly recommend. One important note: I'm 6' tall and I fit comfortably in the long bag, but there's not much room to spare. If you're much taller, you may need to look for a different bag.
