Summary: The bag is almost perfect. The long version might be excessive for me, but I can stuff clothes at the bottom, for next day's use. Haven't found any defects so far. The rating on the bag is spot on. Kept me warm in near freezing and below freezing temperatures. I've tested it close to 25F. However even at slightly higher temperatures (45-50F) the bag gets very warm. One way to avoid this 'excessive warmth' is to open the zipper and let some outside air in.
