I know what you mean about trying to sleep on a bag of spare clothes. Somehow they just aren't as soft as the pillow on your bed at home. I made a couple of versions of pillow containment sleeves, one out of nylon taffeta, and another out of kite tyvek, that I can slip the BPL LARGE inflatable pillow into. The sleeve attaches with 3 velcro strips to the edge of my shortie Thermarest NeoAir. The pillow doesn't sit on top of the mattress, it sits at the end, basically extending the length of the pad. The sleeve keeps the pillow from "squirting" away in the middle of the night. The sleeve is closed on three sides, and open on the edge that attaches to the mattress, so you can insert the pillow. Your shoulder keeps the pillow from coming out the open side of the sleeve. I snipped off the outside corners of the sleeve so I could access the filler opening on the pillow regardless of which way it was inserted in the sleeve. I leave the whole thing attached to the mattress during a trip, and fold it up altogether once I've let the air out. I use my pack and extra clothes to go under my calves and feet. The pillow and sleeve weigh just 1.2 ounces. The mattress weighs 9.2 ounces. My current sleeve is just kite tyvek, and it gives a little extra protection to the BPL pillow, which has lasted 3 seasons I think. For ground sheets I have used kite tyvek, 3 mil poly, a cryo sheet from GG, and a mylar sheet. I like the fabric feel and toughness of the kite tyvek, but don't trust it for water proofness, so I will probably go back to poly. I have piece of GG white spinnaker cloth but have not tried it yet. Zpacks likes cuben, but I don't think the heavy cuben he recommends for ground cloths has a real weight savings over nylon or other options. Is there some way to post a picture on this forum?
