"They do not move with you"

when i received these bottoms, I didnt expect much because polypro is plastic basically. I dont blame the seller for the quality. These pants do not flex with your movement and they were a bit snug on the legs. The one great thing about these is they make a great wind block. I bought these mainly for warmth but they are not flexible enough to move with your body. they kept puklling on my knees. They also make me sweat but its no different than wearing a plastic trash bag. The vender sent them very quickly and I was pleased at the quick response. i just did not like the quality and flexibility. I wish they made a really warm pair of these undergarments that was really warm and breathed.
