Arrowhead Equipment Lost River UQ. MARPAT camo, Brand new condition, it's always been stored fully lofted.

From the AHE Site: 44" wide x 48" long, with a layer of 6 oz Climashield. 2 Loft. The Lost River is cut wider than most fractional under-quilts available on the market today so that is has less fiddle factor, and is less likely to slip to the side during the night, waking you up to adjust the quilt back into place. Based off the New River but with a weight saving 2/3rd length it also compresses to a much smaller size than the NR.
Weight: (approximately) 1 Pound 1 Oz.
Rated to 30 degrees for most users
