I bought these pants to replace Russell sweats that are still functional but very old. These are the same high quality sweats, size is accurate, weight is medium and very comfortable. I've tried Champion, Msport and others and Russell is the best for their intended purpose, working out and dirty jobs. I expect them to last 5+ years like their predecessors.

Update: 12/16/2013 I just bought another pair and I'm adding lounging around comfortably to the intended uses. The quality remains the same, excellent. After a pair has been washed a hundred times they feel a little thinner and lighter so I got a new pair for winter.
