The Peach Percale Cotton Sheet Set is made of 100%.  The sheet set is highly breathable and durable.  The sheet set is moisture absorbing.  The weather is 90 degrees and it is supposed to hit 106 in the next day or two in Texas.  This sheet set will be perfect for a cooler and more comfortable night’s sleep in this hot Texas weather.  I did wash the sheet set before using, and the sheet set stay smoothed and the color stayed vibrant.
