"Skeptical but proven wrong"

"So soft and silky"

This is the best blanket I've ever owned. At first since it's so lightweight, I wondered if it would keep me warm. It works so well. It's so soft and silky.

By golly it works. I was a huge skeptic of the 'NASA cooling fabric' but the elves at Slumber Cloud fooled me! I'm a total convert now.
