As others have said. The wind is all you need for scent control. I don't spend one second in masking my scent, but i'm pretty finicky about wind direction.
Bears have the best noses and I don't do scent control for bear hunting either. We will smell like humans no matter what you do.
Like the most of everybody else,.. I'm more concerned with the wind, over personal scent control. You'll be ahead of the game if you pay more attention to thermals, and the wind. Seems like when elk smell you, they sometimes don't stop running till they are in the next unit.

Stinking is party of backcountry hunting. After the first 3-4 days when you start get nice and crusty. Work, text messaging, social media etc all start to fade from your daily habits and you begin to focus on nothing but hunting. This is when you really begin to get into the mode of backcountry hunting. If you were a pro athlete, you might show up to the game day arena in a suit and tie, but once you put on that uniform and start breaking a sweat during warm ups is when you start getting into gear and get focused. If you were to go to the locker room during half time, take a shower and put on some clean, fresh clothes, you would totally derail that mindset.
You'll feel your dirtiest on day 2 or 3, but by day 5, you'll totally be in the zone. Just go with it. Embrace it. If you can't go a week without a shower and clean clothes, stick to the front country.
I've been on countless 7 day hunts, wash up best I can with a wash cloth, soap & dry off with small terry cloth. Wear same clothes except extra shorts & socks, one pair each, all other clothes stay the same. No scent materials at all, hunt the wind! Success is sweet, enjoy!
