Aerie 0 15 30 45 Degree Down Underquilt 800 Fill Power Starting just Over 2 lbs. Sleeping Bag w/LoftTek Options

Overall, there are a lot of things I like about this item. There are a few things I would change though. Here is a short list of pros and cons.PROS:It is versatile. Being useful as a sleeping bag or under quilt make it a nice multifunction item. So if you are hammock camping or tent camping you are covered, literally. It is my first down camping anything and I am impressed with the warmth it provides. It doesn’t directly compare to other sleeping bags I have had that were colder rated etc because it doesn’t really take time to warm up the insulating layers like traditional sleeping bags do. It is very warm but doesn’t get too hot or hasn’t yet and that is saying something as I am pretty warm natured. It just keeps you around the comfortably warm level. I haven’t tested it below 60 yet but can speak to how well it warms as an under quilt. Hammocks are great but anything below 70 and you have a cold draft under you. I did several makeshift things before I got this item and it surpassed all of them. It has a wide range of hanging methods via several attachment points. That makes it very useful. It matches the pictures in that it can be used as a traditional under quilt or as a sleeping bag around the hammock for a nice protective cocoon. I have my hammock setup with a structural ridge line for a comfortable hang. This fits around that great. Even when zipped, I can still get a decent diagonal lay due to it’s size.CONS:There aren’t many of these and one I am not sure how to best address all of them. The first would be the zippers. The zipper strength seems fine though I wonder at times when sitting in the hammock if too much stress is being put on the zippers. I don’t like the zipper pull tabs. I am pretty sure they were picked to reduce weight so I cut some slack but I don’t like the inside/outside semi-reversible pulls on them. I like that there are two pulls one to open and close that can be moved to either end of the “bag”. I don’t like that only the end of the zipper at the “foot” of the bag has slides for unhooking the zipper pulls from one side of the zipper “track”. The “head” end of the bag has then velcro protective wrap for holding the bag together where the zipper gets to the end of the “track”. That is OK but doesn’t remove stress from the zipper. That end of the zipper track has zipper “stops” at the end of it keeping the zipper pulls attached to both ends of the “track”. The best improvement that could be made to this item would be to change those to be slides like the other end of the zipper so that the zipper pulls could be removed from that end of the “track” as well. It would made it much easier to go from the simple hanging under quilt to the cocoon type hang while in the hammock. It would allow leaving the under attached while just sitting in it without putting stress on the zipper too. As it is, the only way to remove that extra stress and have it hang loosely is to unzip it to the foot of the bag which is a pain because you have to unhook the hammock and feed it thru or around the zipper pulls each time you change from one functionality to another instead of simply zipping/unzipping which could be done with slides on both ends of the zipper.The only other issue is with using the cocoon hanging method. If you have it hung up as an under quilt, it lifts the quilt from the around the zipper because that is where the attachment points are. The catch with that is that it also lifts the cocoon off of you when it is zipped. The cocoon would be much more effective if it fell down on top of you like a sleeping bag would. The issue is that disconnecting or loosening the under quilt suspension is challenging from inside the hammock. I would recommend some sturdy mitten clip style hooks for attaching the under quilt to the 1/8 elastic cord. The only other thing I can think of to improve how that hangs would be if the bag had additional attachment points lower on the sides. That way, the under quilt could stay lifted up and in position but the portion of the sides above those attachment points would be free to fall down on top of you keeping you extra comfortably warm. In around 20 degree temps, I would think that would probably be how it would need to be positioned for optimal warmth.Overall, this is a great product that I do not regret purchasing. I can just see a couple of things that could easily be changed to make this a truly exceptional item at a decent price. [...]
