For me, a pillow is a must–preferably something made of down. Air pillows tend to be bouncy, and stuffing clothes in a stuff sack means that you aren't wearing them to bed–also it doesn't match the comfort of down.
At present, I use a WM Cloudrest at 128 g = 4.51 oz. The pillow has an included stuff sack and drawcord–I'm wondering if removing it would get it down to around 4.00 oz. However, I was thinking of refining my clothing system to include a down vest or jacket (something, say, less than 8 oz) instead of the microfleece exp weight baselayer I now use as my midlayer. I could wear the down midlayer around camp or when hiking in freezing conditions, and then stuff into a stuff sack at night to produce a great pillow.
I suppose the question comes 'down' to (no pun intended) the following: Will removing 4 oz (or more) from my body to use as a pillow be offset by a corresponding increase in the weight of down I'll need to have in my sleeping bag to compensate? In other words, what is the ratio of clothing weight utilized as a pillow to the ratio of sleeping bag weight needed for insulation. Is it something like a 1:1 ratio or a 2:1 ratio. If the former, then it would seem that one doesn't benefit in the least by utilizing one's clothing as a pillow, since every oz you are using for that purpose is going to require an additional oz in your sleeping bag/quilt.
There ought to be a scientific way to determine this ratio, and get this figured out!
I have been meaning to whip up a pillow for a while. Just finished it in about an hour. It is made of 8D and 850 down, 3 baffled chambers made with nanoseeum mesh. Exactly 2oz of down fill, 19×13" 4.5" loft. Weight is 2.3oz. It has a pouch to put an air pillow or clothing in. I am going to make another one to go over my Montbell UL pillow seen in the picture. I'll post this in MYOG as well.
