I've bought a lot of different sheet sets and brands over the years and have to say I'm so glad I tried Linen Republic. My husband and I like our sheets cool and although I've bought a lot of different sheets that are "all cotton", have been disappointed by many brands. Several have still felt hot, as if they were partly polyester. I have one set of 800 count cotton, which are very nice, but are too heavy for warmer weather. These sheets immediately felt cooler and more comfortable. I didn't even tell my husband I had bought new sheets, but after a few days asked how he had been sleeping. He said he had noticed that he hadn't been waking up so much. I told him I had been sleeping better too and think it was the sheets. Was so happy I came back a few days later and bought extra pillow cases.
