Getting an 11' Argon from Dutch, and looking to buy a pillow that I can take backpacking. I just purchased a WL Full Length Summer Series Underquilt, and I have a 20* Sierra Designs Down Bag that I will use as a top quilt. When I hang inside I just use my full size pillow from my bed, but looking for something of substantial size, yet light and packable. Does such a thing exist? Not opposed to Down, Synthetic, or Air pillows. My options are pretty open.
