When I first got these sheets they didn't have a certain feel about them, which I should have put them through the wash first but, oh well. The first night sleeping with them I was a little concerned because they felt cooling and I don't like sleeping chilled, but I was also done with waking up hot and sweaty. These sheet don't really cool as much as they regulate the temperature. Even with a bunch of blankets piled on I never really overheated while I slept and they really helped with keeping me at a constant temp. No more did I have to wake to grab another blanket and I didn't have to take a layer off. And after washing them they really softened up. ALSO, they have a nice corner strap to keep the fitted sheet tight on the mattress, something my dog likes to put to the test, but it stays on like a charm!
