I am in general very happy with these sweatpants; I run in them outside.  Why four stars instead of five?
1) I originally purchased these to run outside when it was chilly.  However, they provide minimal warmth.  Probably my fault for not doing more research first.
2) I am 6'7" tall, but even so, these pants were too long.  My wife was able to easily hem them, so not a big deal ... but for "tall" pants, they are VERY tall.
