I really like the simple practicality and durability of these plain Russell crewneck sweatshirts.  My old ones (large) were getting a bit ragged, so I bought a new batch expecting the same fit.  However, the newer ones apparently run MUCH larger.  What they previously considered "large" is now medium (presumably to protect the fragile vanity of fat-but-in-denial men).  No problem... I got them in medium and have been very happy with the decision.
