Review on Alplive T400 Ultralight Backpacking 32-50F Down Sleeping Bag - 27Oz Ultra Compact 650 Fill Power Envelope For Hiking, Camping And Backcountry - Lightweight & Compressible by Benjie Swindler

Mine just arrived, as I'm prepping for a five-day outing where the low temps will range between 58º and 65º. My regular down sleeping bag was just too warm at this location last month. I've been experimenting with using my bag unzipped like a quilt, with good results, except my heavier down mummy bag is oddly shaped when unzipped and the hood area at the head is all kinds of awkward when using the bag like a quilt. I wanted something. . .rectangular. I'm a big fan of down, and was looking at options like the ZenBivy, but that appears really expensive for what is basically a quilt. So I was shopping for down quilts when I ran across this down sleeping bag, and I verified that it can be fully unzipped and used as a quilt.Now that it has arrived, I'm really happy with it. Here are the main things I want to get across to potential buyers:-It's very high quality.-Mine has ZERO ODOR to it. The reviewers that wrote about odor really had me nervous about this purchase. I'm happy to report that mine has no odor whatsoever. I say: Buy with confidence!-The zippers are really big and strong. I have confidence in them.-It has two zippers: One for the foot box area, and one for the rest of the bag. They meet around mid-calf area, and can both be undone to make a big rectangular quilt, which I mainly intend to use this bag.-It comes with a very high quality compression sack. Not cheap garbage.-The 20D nylon material of the bag is very smooth, almost like thin plastic. I expect it to be highly moisture resistant.-I've unpacked mine and it's still lofting up, but there isn't a tremendous amount of loft to it. It's a thin sleeping bag. Consider this a warm-weather bag only. I would not use this as my only bag below 50º. I can see packing this along with my heavier down bag and using them together for really cold temperatures.-I think this is perfect for summer camping if you're torn between being a quilt sleeper and a bag sleeper. I intend to use this as a quilt, but I have some peace of mind that if it gets a bit cooler, I can zip it together as a rectangular bag. It is thin and lightweight enough that I can definitely see bringing it along with my heavier down bag for cold nights, to use an an extra quilt or bag layer.-Others recommended using a bag liner if using this as a sleeping bag, saying this is a bit TOO moisture resistant. I think that's good advice, as the material is almost like thin plastic, while still being smooth nylon. A cotton bag liner will help you not drip sweat back onto you.-I think it's the perfect lightweight down quilt!
