I have a Remstar Auto M-Series cpap. I also use a nasal mask, but I have a nasal pillow around somewhere. I'll definitely try the nasal pillow next trip. I'm also going to sew up an insulated cover for it. I'm going to use the thin foam that was wrapped around my new Samsung TV I just bought. I believe it is very similar to the IX people are using for under quilts. I will either put the cpap in the hammock with me (under my quilt) or will rig up an insulated box/cooler for it with an air vent and several of the handwarmers.
