A recently completed extreme custom job. A customer of mine, who has taken the MARCY 20 to task up in Alaska btw, inquired as to whether I would be interested in doing a pretty extreme custom quilt.
The goal was for the design to include the following:
-Able to be used in both blanket mode and quilt mode.
-Have sleeping bag mode, fully wrapping the body and sealing up to the neck somehow
-Be rated to -40. (yes, you are reading that correctly)
-Come in at sub 4 pounds.
I read the email and immediately put an ad on Craigslist.
For Sale: 4 sewing machines: Juki, Tacsew, Pfaff, Singer
Local Pickup only; they are on the front lawn. ;-)
Joking aside, quite the opposite actually. This was super exciting. Long story short, I built a prototype first, followed by the actual bag. Final output is in the pics below, but first some specs.
Weight: 3.875 pounds
Loft: 12 inches, I repeat twelve inches!
Down: ~45 ounces of 850 FP HyperDry water resistant down
60" wide (excluding side draft collar)
70" long (excluding top and bottom draft collars)
Shells: Outer ARGON 90, inner, ARGON 67
Offset top and bottom draw cords, cinch around the top and bottom draft collars. This plugs the footbox hole and cinches nicely around the neck at the top.
38" of omni-tape to form the footbox, 42" zipper from the top of the footbox to the top of the quilt for a fully enclosed sleeping bag. Both the omni-tape and zipper were each sewn offset to the edge, creating a draft collar along the entire side of the bag.
Can be used in blanket mode, quilt mode, or sleeping bag mode.
Mulling over making this a MAMW offering. Feel free to email if you have any questions!
