I carry a small pint size ziploc bag with several pair of nitrile based gloves (purple)...and some packaged wipes (like you get at when you eat ribs)...
Basically it is for clean-up...as your odds of picking up something for gutting a deer is probably lower than from shaving...but it does not take up significant room...
And after the gut pile has been removed from the deer, I go back and harvest the bladder to later extract the urine for my own deer urine...it does help with that...especially if you intend on eating that PB&J sandwich afterwards...
