I've always used the military camo sticks, the stuff that looks like huge chap stic tubes.
Really hard to get off and sometimes have to soften it with bug repellent to get it on, I think this year I may try the Scent Schield camo pack, it is supposed to be very easy to wash off, which means it will probably run off with sweat...oh well what are ya' gonna do...can't get it on, can't get it off....or it won't stay on.
Time for several bottles of cabernet or merlot before bow season, need the corks
