These pants are great. This was actually the second pair Ive bought. I do think the sizing maybe a tad bit off. I normally do not wear a small in anything but in these pants I do. Im 54 approximately 125 pounds and a size small fits perfectly! I wear these underwear other cotton knit pants when I run/walk. They don't ride up and they keep me plenty warm when the temps are below 30 with a slight breeze.
