I'm a big guy, so getting a nice, snug, well-fit undershirt is a bit of a daunting task. I decided to splurge on these a while back just to see if there was a significant improvement over the cheap 12-packs of undershirts I would buy for less. Out of the package, these were great. Loved the snug comfortable fit, I was very happy with them. But after a couple washes and a few more wears, they very quickly expanded, becoming very loose, flimsy, and not comfortable at all. I've tried all I can to shrink them back down, but to no avail. They stretched out too much, and I'm back to the cheap undershirts I used before.
