I recently purchased a Nunatak Arc Edge quilt that I intended to use as a summer quilt, but it was just too small for me. It is a size Medium. It is 5'10" long and about 43" wide. It's purposely meant to be cut smaller to shave weight. If you are looking to cut your summer load this will do it. I say it weighs 13 oz, but that is with a heavy duty pad strap which, if removed will probably cut at least another 1.5 oz but I am leaving it up to you to do that.
I'm asking $225 shipped. As you can see from the link it retails for $332 and they usually have a substantial wait time for production. Please PM me if interested. Thanks!
