I found sheets after my sister recommended the brand while visiting here in California one weekend. I had already done so much much searching and compassion of hypoallergenic pillowcases for my husband, and I just wasn't ready to spend money on something that might not be top quality. After a weekend sleeping on her guest bed, I was hooked! I ran out and bought a pair as soon as we got home. They were very breathable and cool in the summer with a partner sleeping next to you. We live in AZ and with these, both sides of the pillow stay cool all night. I have not slept so easy in such a long time. Not to mention the high quality fibers did not trigger his allergies.
