DO NOT count on the temp rating for a comfortable nights sleep. For the life of me I dont understand why these bag manufactures feel the need to put an absurdly low rating on their bags in order to sell their product. Sure you wont freeze to death, but isnt the point of picking bag to find one that will give you good nights sleep, NOT tending to the camp fire ALL night long in order to catch a few ZZzzz. Anyways, this rating system seems to be the norm of the sleeping bag industry... craziness! I wish someone would step up and be a straight shooter here! The only nice thing I can say here is that its very light and easy compressed, but so does a simple bag liner!
