$260 - Moonstone Delta Liberty Ridge 0-degree Down Sleeping Bag
Sierra Trading Post has the Moonstone Delta Optima sleeping bag for just 40% off. Rated to 0-degrees, this is an 800+ fill power down sleeping bag with a highly water- & wind-resistant Pertex shell. I’m a big fan of Moonstone sleeping bags. I’ve owned two and don’t have any doubt that this sleeping bag will match or beat the 0-degree rating. One other great add-on to this bag is the mesh pocket in the hood - great for keeping a watch alarm audible for early alpine starts.
