The sheets really did work, they kept me cool and comfortable, all night. The other bonus was, I woke you and didnt have any "sheet marks" on my face or body (like when cotton sheets wrinkle and you are left with the imprint  on face or body). I also love the fact the elastic around the corners of the fitted sheets hold the sheet firmly in place. Well done!!
The one small con I have is; if you have dry feet, the sheets seem to snag or scratch at you feet. (Doesn't hurt just feels odd at first). I'm a runner so I have calluses on my feet.) The feeling is minimal and once I was in bed and comfortable didnt notice anything.
I plan to buy these sheets for Christmas gifts for family and friends.
