Double Black Diamond
Lightweight, inexpensive down throw, can be converted into many things—a DIY dream.
The Double Black Diamond quilt is the brand name of the "Costco Quilt" that people talk about in the DIY forums. I received two of these as a gift. From what I understand Costco sells them from anywhere from $20 to $35 depending on the year, and apparently they aren't always available. I had them bookmarked on Amazon for around $50, but they are also showing up as currently unavailable.
This is a light, rectangular down blanket with sewn through seams. My scale shows 15.6 ounces with the stuff sack. I use it as a top quilt for 50 degrees and above. I initially taped a foot box to see how it would perform before I sewed it, and never got around to sewing it. Not as aesthetically pleasing as a good thread injection job, but I have concerns about down leaking if I sew it:
I've tried sandwiching one of these between an underquilt and a hammock for extra bottom warmth, but it doesn't work. Some sort of suspension system would have to be rigged up.
I know a couple of hardcore DIYers that tried to make solid underquilts out of two of these layered and sewn and shock corded, but they always ended up sleeping cold around 50 and below.
Sewn through and thin:
For the money, these make an awesome warm weather top quilt and they're great to have around when you're outfitting others or want to boost your warmth. They do leak quite a bit. I've not noticed feathers poking out of the quilt itself but when I wear my Patagonia Capilene 2 black bottoms to sleep they are covered with tiny down bits in the morning, like I slept with a husky or something. Still an awesome value and could be used for many different things.
