To quote the regulations:
Deer hunters’ orange apparel. When hunting deer with firearms you are required to wear one or more of the following articles of visible, external, solid blaze orange clothing: a vest, coat, jacket, sweatshirt, sweater, shirt or coveralls.
The instructors for my son's hunter safety class emphasized that it had to be a full vest at a minimum, technically no shoulder patches or even an emblem, if an officer chose to be literal. Also, camo orange definitely is not considered adequate (see SOLID BLAZE ORANGE).
Not knowing the full specifics, it would seem that a substantive vest combined with a solid blaze hat/cap SHOULD be adequate to make you visible, and hence in conformance with the intent of the law, i.e. be visible so you're not mistaken for game. The DNR officer has some discretion, could be strict: OTHO, if too picky a judge would in all probability throw out a citation if issued and you chose to fight. Ultimately, the rule is for our protection, not in anyone's best interests to "cheat" on this one.
