The Flextail pillow is too expensive, and the least comfortable. It has a plastic inflatable core, which makes it feel like a balloon, it is not high enough for side sleeping, and the "ergonomic shape" does not cradle my head and the valve sucks. $20

The Bisinna pillow is a standard hollow fibre filled pillow. It is ultra light at 180 grams. It is the thinnest pillow as is compresses too much, but it is the warmest, and I like to bring it as a secondary pillow to place on top to get more height when side sleeping. $4.

The Naturehike is ok. It is the rectangular model, and I got the case/topper to go with it. The pillows sides are higher than the center to cradle the head, which is annoying when side sleeping. Also the topper did not have a pad strap, so it slips around a lot. $15

The Widesea has good height and less cradling making it good for side sleeping. However it does slide around. $3
The pillow cover/topper is from another pillow which broke after 4 years of use. The inner inflatable pillow has a similar shape to the Widesea (I bought it to use in this topper), but had a flatter top and was perfect for me. $10
