Review on Elegear Cooling Pillow Cases For Hot Sleepers, Japanese Q-Max 0.45 Cooling Pillowcases, Both Sides[Cooling/Cotton], Breathable Soft Pillowcase For Hair And Skin, Set Of 2-White (Standard (20" X 26")) by Joy Janes

Years ago, I learned (not without some degree of pain) that the better part of valor is to let my wife manage nighttime thermostat settings. Unfortunately, since I tend to sleep a little warmer than she does, I woke up for years in the middle of the night sweaty and uncomfortable.No more! It is no exaggeration to say that the Elegear cooling blanket has changed my life in a very positive way. (See my video review of that product for details if you're interested.) As a result, these pillowcases were an easy sell. After about two weeks of using them, I can't really imagine being more pleased. For less than $25, my life has improved again!The magic behind this product is the shiny side (which is an 80/20 nylon/polyethylene mix) that is remarkably cool to the touch. You can see (in second photo) the contrast between that side and the (100% cotton) warmer side on the reverse. I am almost certain that I will never use the warm side on my head! When I climb into bed, I position myself on my side, place the puffier pillow (again, shiny side up) between by legs for back support, lay my head on that cool (flatter) pillow, and I am out in minutes! Sheer wizardry.I do find that after a couple hours with my head on the pillowcase, the cooling effect recedes somewhat. This is easily remedied with a 180-degree rotation of the pillow and repositioning my head on a not-recently-used portion (which allows the part where my head was to cool back down). With my cool head is restored, back I go into dreamland!If you sleep on the hot side, please try this product! Honestly, the fact that I spent so little to change my life so profoundly makes me feel like I got away with something - in a very good way!
