I generally like these synthetic tee shirts.  Over the years I've found that they hold up longer than cotton ones, which develop holes.  These are colorfast and comfortable.  A couple of shortcomings:  1) there is less of a difference between front and back than I see in other tees, and I frequently put them on backwards, feel the difference, and have to take them off and reverse.  The painted-on labels eventually flake off, so you lose that cue to the proper direction.  2) They do get little pulls when snagged by thing you brush against, including jagged fingernails.  They still hold up well, but the snags are permanent and unsightly, making them unsuitable as your top layer.
