It is certainly an interesting option. Thanks for bringing it up.

If a person really needs a pillow, and $185 is not too dear, that is certainly a nice one to get. Not so much if you don't really need a pillow or the price seems too dear.

Camping and hiking I never bring a pillow. In the heat I sleep without one and it seems cooler. Other times I roll up a towel, jacket, spare clothes to make a workable pillow. Generally I'm tired enough after a day in the field that I'm out like a light and the deficiencies of my field-expedient pillow make no difference.
