In the military, for everything but training suits, it was use once and dispose. But like I said, I use them for about three seasons and then get new. I have not been busted once due to odor. I have been busted:

1. on the way to a stand;
2. while coughing;
3. while farting;
4. and once for muttering a curse word at a buck that wouldn't come in while unbenownst to me there was a bigger buck behind me.
