What struck me as soon as I opened the packaging and lifted them out what how lightweight these fleece lounging pants are. Yet at the same time the material was ultra soft and snuggly. I put them on and they fit perfectly. And they've worked out in real-world use. During the cool evenings of a Northern California spring they keep me warm while watching television or making dinner. They're a little too casual to be worn outside, and they would not make good jogging pants, but for their intended purpose, which is to keep you comfortable around the house, these are an excellent choice.
