MOONSTONE PACIFIC CREST TRAIL LONG LEFT 800 DOWN SLEEPING BAG EUC I bought this bag recently, and tried it on, then washed it. My honest opinion is that this bag is good down to about 20°F, and a little lower with extra clothing. This bag has 21 ounces of 800 fill power down. The baffling in Moonstone bags is trapezoidal, and if you look at the pics, you can see that the baffles appear to alternate between long and short. If you open the bag and look at the inside, you can see that those baffles alternate short and long, giving each section a trapezoidal profile. The objective is to minimize the possibility for cold spots. The baffle spacing is pretty tight, averaging less than 5 inches. You can see that there are 16 sections below the hood, whereas most sleeping bags now have 13-14 sections for a similar length sleeping bag. The hood is roomy, form fitting and very comfortable. One pic shows the back side of the hood. I always wear a hat and I like to have a small pillow inside the hood, and this hood looks perfect. The loft is about 4-5 inches, as you can see by looking at the bottle of water. The bag has a plush draft collar at the neck. The internal dimensions are about 60/50/40 for shoulders/hips/feet, which makes this a fairly trim bag, although a slender person could wear a lot of clothes in this bag. This bag would be great for a person up to probably 190-200 pounds, or a smaller person who would like to be able to put extra clothing and perhaps a quilt inside the bag. The bag is a long, and my 511, 175 pound frame had a lot of length to spare, and although I think the bag would be suitable up to about 66, Id be cautious, and suggest a maximum height of 64 to be safe, unless a person has personal experience with Moonstone bags. The listed finished size on the tag, 30″ by 83″, refers to the internal dimensions of the bag. The lining color takes a little time to get used to, but I assure you that if you are sleeping in this bag at 4AM on a. 20°F night, you will be warm as toast and not thinking about the color. After laundering with Nikwax Down Wash and drying thoroughly, the bag has been stored in the storage sack, in a clean spare bedroom. No pets, no vermin, no stains, rips, tears, damaged seams or odors. The only mar is the marking inside where a previous owner apparently wrote their name with a Sharpie. So the specs are: Pertex breathable shell Locking full length zipper 21 ounces of 800 FP goose down 60/50/40 measured girth at shoulders/hips/feet Nice draft collar Full draft tube behind the zipper, with tape to prevent zipper sticks Trapezoidal baffles Modern hood with double drawcord. Roomy trapezoidal foot box Total weight is 2 pounds, 8 ounces on my digital scale. Includes non-original stuff sack and aftermarket mesh storage sack.
