I ordered a custom Integral Designs Renaissance bag a couple months ago. I canceled the order the next day after they said how long it would take to produce.
Well to make a short story long the bag is complete and being sent to Pro Mountain Sports in Seattle, they have a cool website by the way. I do not have to buy the bag or anything but wanted to let you guys know in case you wanted it.
It is the Renaissance with a half length zipper with 3 layers of Primaloft on top and one layer on the bottom. The bag should be closed to 5 degree rated now and with a 64" girth still have ample room for layering. The standard bag has layers of 2 and 2. I would buy it anyways if it were not Christmas.
