I would love to be a rough and tough guy who scoffed at the use of a pillow. But, I'm not. I need some creature comforts.
Last Xmas I received one of
these as a gift. Its basically the same as the one you are linking, although it looks a bit bigger. It also includes its own stuff sack.
It is better than stuffing some clothes into a stuff sack. Consistent padding. But, it flattens out a bit. This is OK with me because I like to sleep with a super thin pillow anyway, almost like no pillow at all. If you like one of those sick 3 inch firm pillows, or a down effect... then just forget it... you won't like it. Grab a piece of
compressed polyester and throw it in your pack. It comes in various thicknesses (1 inch, 2 inch, 3 inch), its cheaper, and is available a wally world and joannes fabrics. Throw a shirt over it and you're ready for bed.
I sometimes wonder if pillows such as this operate more on the placebo effect. "I have a pillow, therefore, I must be more comfortable".
