Coax Mike out of his briefs:

Materials > Skin Hip > Poser Surface > Color Texture > Image_Source

Choose "/Runtime/Textures/DAZ/Characters/MilMan/M4/M4Smpl_malebody.jpg" instead of "/Runtime/Textures/DAZ/Characters/MilMan/M4/M4Smpl_brief.jpg"

Of course, it may be a little disturbing for some to see him that way...
