  • They really work

    I have to admit, I was skeptical that these sheets would be worth the price, but I was desperate for some relief from my hot nighttime sleeping so I gave them a try and I have to say that they really do work. They look and feel just like regular sheets, so once again, skeptical. But I would buy another set in a minute. I also bought the Outlast comforter, mattress pad, and pillow, and the combination is great.

  • My 4th Set!

    I have completely stocked my linen closet with these sheets and pillow cases. I would say I was a VERY satisfied customer and recommend it to anyone in the market for new linens.

  • Very cool

    These sheets are exactly as advertised. They are very soft and smooth and keep my husband from sweating; I am buying another set.

  • Expectations

    We recently ordered a new memory foam mattress and I was aware of the problems with heat retention. In order to mitigate this issue I ordered the Outlast mattress pad and the sheets. I tend to sleep hot so I was hoping/expecting these "not too hot, not too cold" products would help me regulate my temperature. In the end, I believe they do work however I was hoping I would be cooler. I don't seem to sleep hot anymore but do feel "comfortably warm". I would prefer to be cool, but for now this is a huge improvement.

  • Not different from any other sheets

    I have not noticed any difference in temperature at all. They do not help keep you cool at all. I did follow washing instructions carefully. They do have a nice enough feel to them, but they do wrinke terribly. Not worth even half the Overstock price.

  • I've been a hot sleeper all my life

    I'm a hot sleeper and my wife is a cold sleeper. This has presented us some issues in terms of the products we purchase. Either I'll like something and she won't, or vice versa. We read up on Outlast and decided to bite the bullet and purchase everything, including pillows, a mattress pad, sheets, and a new comforter. When we laid everything out and went to sleep that first night, the differences were apparent. Everything is cool to the touch, and the sleep system does a great job of taking the excess heat away so that I can enjoy a night of sleep without constantly shifting my body or flipping the pillow. My wife says that the system stays at a good temperature for her and doesn't cool down to the point of making her feel cold. Needless to say, we're both very impressed. We already have an adjustable bed due to our different needs for firm vs soft sleeping, and these items finished off exactly what we needed.

  • Love these sheets!

    First of all, the sheets are extremely soft and comfy and I love the green color (think mint choc chip ice cream!). Secondly I have noticed a marked reduction in the amount I sweat during the night. I used to vacillate between covers/no covers throughout the night, but with these new sheets I can remain under the covers without overheating. My husband, who is a cooler sleeper, loves them too and says he has slept better since we got them.

  • Nice feel to the fabric

    These sheets are very smooth, wash well, and I believe they do help regulate your body temperature at night. They're not a miracle, but I sleep better than I used to, without waking multiple times because of overheating.

  • Temperature controlled sheets

    I decided after getting these sheets that I will only ever buy temperature regulating sheets for myself from now on! :D I have Ehlers Danlos Syndrome and Dysautonomia (a dysfunctional autonomic nervous system) so I do not regulate my temperature well at all. It can make me very sick. These help a lot though since my problem is extreme it is not a 100% fix. But they have made a big difference. I definitely recommend them for everyone, even if your internal temperature control works.
