I think it's a really high-quality product. I was surprised at how warm it kept me. They're very easy to put on and fasten above the knees, so your knees stay nice and warm too. When the boys go out to play, they are sure to have well-warmed Achilles tendons, knees, and entire legs. It is interesting that we were among the first to test this product, as it was developed at the Technical University in Liberec.
