The 3.6 oz Climashield was cut to 6'X3' and stitched toward the bottom of the quilt - I didn't think utilizing insulation past the 3 and 9 o-clock position would be of much use. The quilt was then tapered at the bottom corners in order to minimize even more material and to keep the quilt from bunching. The outer shell is 6" wider than the inner shell. This keeps the insulation from compressing when in use which maintains its full R-value. The channels are sewn into the Nylon and double stitched. Using a stuff sack, the hammock compacts to about 6"diameter X 6"tall. The hammock kept me very comfortable at 35 deg. F while inside a 20 deg. rated sleeping bag. In my trial test at 35 deg. F, when the underquilt was removed from the hammock, it was uncomfortable just using the 20 deg. rated sleeping bag alone. In other words, you could feel the cold on your back without the underquilt attached. I am 6'1" tall and the 3/4 length kit works perfectly for me.
