Query: A bit expensive, but works really well!

I bought this product for ~ $20, but I have to admit it's really nice. Right when I first opened it, it was pretty fluffy. I read previous reviews that I would have to wait at least two hours to get a good fluff, but I only had to wait 7 minutes! I got a small and it's a good size to bring camping or to have in the car. I usually sleep with two pillows, and this single pillow works fine. The denim feels more like a suede. Overall, very good product. Five stars!
