I have been looking for new pillows because I have been having neck pain and I sleep hot so I thought I would try these. They came vacuum packed and fluffed up pretty quickly. They also came with extra filling that you can add if you want them a little firmer. I love that because it make the pillows somewhat customizable. They do have a nice cool feeling when you lay on them. I have only used them for a couple of nights but so far they are really comfy and mold around you to provide support
