  1. Great product

    Posted by S. Khan on Feb 15th 2018

    I was skeptical at first, but was pleasantly surprised receiving the product. The clothing material is very soft and the design is exactly the way it is in the pictures. The fit is great too. Thank you. Will be ordering more.

    such a cool shirt for a cop. And then of course, I have to explain what “probable cause” is to civilians.

    “ yes dumbass, tag lights are a legitimate reason to stop you”

    Great quality shirt, shirt was a bit tight in the arms but I like that but could see someone else complaining about it. Awesome shirt and love the weird stares I get when I wear it.

  10. Awesome shirt!

    Love the fabric, the feel of it, and it is sized right. Washed it twice with no fade or shrink. Very witty. Gets a lot of second looks.
