The Perfect Bag
This is the first bag that I, as a cold person, have been consistently warm in. Despite never coming close a trip that involved sub-zero temperatures, I've found that the truly amazing thing about this bag is its ability to adjust to your temperature, independent of the temperature outside. I've used it in 60 degree weather, and 15. I was comfortable in both temperatures.
