Beautiful color! Wonderful fit! No, they're not SUPER-soft--but definitely soft enough. Just like the percale sheets I remember from my youth, they've a 'crisp' finish & don't make me sweat. They might soften the more they're washed, but I love them now, having been washed only once. Amy wrinkles flatten out when put on the breed. And they even fit my mattress pocket!

I keep several of these on my travel backpack and use them to close bags, attach luggage together, zip tie my wallet chain to my belt loop, and in so many other ways. Wonderful product.
