I purchased this quilt to use in the summer and "shoulder" seasons. My lightest bag was a 20 degree bag, which is simply too heavy and warm for summer use, but instead of getting just a lighter bag, I thought I would try a quilt for the weight savings instead. I am extremely pleased. The quilt snugs up nicely and has never given me a draft or cold spot, even without using the straps. On a colder night, I engaged the straps at first, but when you are 58 years old and make a couple nighttime forays to relieve yourself, sometimes a quick exit is important, and I did not use the straps again, just engaging the 2 snaps up near the neck. Worked like a champ. If you've ever had a zipper jam up and it turns into a race to see if you get free before it's too late, you will appreciate how important that is. I was skeptical of using a quilt, but am no longer. It kept me warm down to, and just below it's rating. It is Much Easier to get into and out of than a sleeping bag. It lowered my base weight by just over a pound, and packs down incredibly small. The fit and finish of the bag itself and all the seams are Top Shelf, and I anticipate many nights of blissful warmth from this quilt.
