RE: Let's talk about scent sprays.
In line with what Mikey said - I try to toss my Scent-Lok stuff in the dryer before packing it up when I can. Like he said, sweat/moisture gets on the clothing and then you lock it up in an air tight bag and that's just a recipe for nasty scents to start happening. This is especially true after early season/warm hunting condition hunts.
As for the mask, it drives me nuts too but I still do it. It's kind of an acquired taste and something you get used to after awhile - to the point where it's no big deal anymore.
My hunting partner/cameraman Mike (dukemichaels) has been taking chlorophyll tablets this year and practicing the same scent routine I have and hasn't been busted once. We had some deer at 10 yards last week putting their noses up because they smelled something out of the ordinary, but they never spooked and blew out of town - and we certainly could have shot them if we wanted to. Keep in mind this was in some brutally humid conditions when we were both sweating from walking in, climing up, and getting our gear all situated.
In regards to soap/shampoo/sprays I've traditionally used the HS or Scent Shield stuff and been happy with it but I switched to Dead Down Wind this year and so far so good. We'll see how the rest of the year pans out, after all it's still early.
