I've been using this for six months. The breathability is excellent, and it was very comfortable to sleep on. However, either it didn't suit me, or my straight neck condition worsened, and I'm sadly putting it up for sale. The pillow has been washed with a shower, and the cover has been laundered. I wasn't sure how to pack it, so I'll send it in the simple packaging shown in the photos. The main body is folded, but it will probably return to its original shape if you pour hot water on it. Please understand this before purchasing. Please note that this is stored, inspected, and measured by a non-professional.
