Because you just can’t have enough safety/armored jackets, right?  Another Frank Thomas English jacket with the zipper on the wrong side.  $30.  Still more than my other two, which are nicer, and this one does not have removable armor, but it is still in great shape & is a bit lighter than either of the other two. Mostly vented, but not quite as much as the other Frank Thomas one.

The Bad:  Can’t wear it about 80 deg F outside.  Too hot for that.
