For many years I used the Graham Medical Small @ .6 0z (17 grams). This was a great pillow when it had dual chambers. After I could no longer buy the dual version (though the single is still the lightest pillow available) I started looking for a replacement and finally settled on the Exped UL Medium @ 1.6 oz (46 grams) which gets me a great night’s sleep (coupled with the Thermarest’s Neoair Xlite Women’s sleeping pad – which I also use with a Big Agnes Cyclone Chair for a comfy seat in the wilderness: http://www.theultralighthiker.com/cyclone-chair/ ). Here is a comparison of what’s available: https://backpackinglight.com/ultralight-inflatable-pillow-gear-guide-jordan/ I would certainly be prepared to try Neoair’s Size S (might be warmer on a cold night – 1.9 oz or 54 grams) or Big Sky’s Dreamsleeper Deluxe @ 1.4 oz (40 grams). One thing I like most about Exped’s is it is asymmetric so that you can choose from a number of different configurations.
