Yes! These are COTTON sheets! They feel crisp and cool, yet soft! They are slightly more sheer than I expected, but they have plenty of “body”. I love snuggling in them when I go to bed, and I am convinced that if they were thicker (or heavier fabric) they would be too hot. I do sleep hotter than my spouse. These sheets do not make me sweat at all. My husband says he sleeps comfortably temperature-wise, too, and he typically stays cold. I always wash new linens before using them. I washed in cold water and dried on medium heat They came out of the dryer slightly, but not overly, wrinkled. I did not feel they took too long to dry, and I felt no ironing was needed. Never, ever ironing! I typically change my linens weekly, but I got busy and skipped a week when I first used these. I definitely noticed these sheets felt fresh even when I finally took them off to laundry. The fitted sheet has elastic all the way around. The extra deep pockets give me an extra 6 inches or so… all the way around the bed…to tuck under the bottom mattress. No more problem with corners popping off the mattress at night! The flat sheet covers both mattresses on both sides of the bed, and has enough length to tuck at the foot of the bed. The king pillow cases fit my gusseted pillows perfectly with enough room for my pillows to expand fully in between the seams. There is an extra fold of fabric near the end opening to help conceal the pillow and to hold the pillow inside the case. I ordered white. The color was even throughout these linens. My set was sewn well and had no flaws. They have been washed and dried twice without any issues. I am happy with this high quality set and plan to order another set, or two. I do recommend these sheets.
