I have bought two packs of these value-priced Fruit of the Loom men's t-shirts to wear to work. I do welding, and what I need is durable, dark colored and inexpensive t-shirts that I wouldn't worry too much about ruining. These ones fit the bill very nicely. I bought a pack of 4 black t-shirts and another pack of 4 dark blue ones, for $10 a pack which is a decent deal.
The t-shirts are 100% cotton, they fit well and feel very comfortable. They have one front pocket that I use to stick my ID in, so it comes in handy. My t-shirts have been through numerous washing, and they are holding on well, no shrinking, fading, or tearing so far. The only wear I have detected is a few tiny wholes I have burned in one when welding - no big deal, I will buy a couple more packs for replacement.
