These patches are made with the same newest technologies using Thermoplastic Polyurethane (TPU) material the same as our raid vest patches that provides a patch that is not only highly durable, but highly reflective.  We've tested these in pitch black conditions using a simple three "C" cell maglight and while you couldn't see the wearer or even their silhouette, the patch was extremely bright and clear.  See the test for your self:
