I really loved how light and compact this pillow is. I often opt not to take a pillow backpacking, since it takes up too much space and weight (even the compressable Thermarest ones.)
I used this the first weekend I got it, and have used it on a plane ride as well. My only complaint is that the material is a bit "slippery," so sometimes the pillow would slip out from under my head at night. The x design helps that, but I learned to leave it only half inflated or it still would pop out. But it's already been put to good use several times!
