I read lots of reviews before I made the decision to buy these. Glad I bought them - they do, indeed, fluff up in the wash, which is important for flannel, as the raised nap is what keeps you warm (it traps your body heat, much like an animal's fur). They are just the right weight for our climate, nice and soft. I have slept so well since putting them on the bed! They are well made, and I will be surprised if they don't last a good long time.
