Yup, quit wearing synthetics, there is NO advantage over wool and silk. The merino wools are softer, warmer or as warm, feel dryer, and insulate when wet. What to guides in the mountains wear...not synthetics!
Wool has natural antibacterial activity, no silver necessary. Look to Wool Power, Smart wool, etc.
Synthetics have their place, but using primarily wool and silk you should have less problems. Like you I sweat a lot and stink most of the time...usually from smelly hockey equipment and I use a few specific things now. I use the Hunter's soap from 3 rivers, it is a natural oil soap, the oils fight bacteria and although it is refreshing smelling when you shower (nice odor), it is gone when rinsed and you don't get the weird clammy sweat that the scent killer type soaps leave you with later on. Also I use a scent killer type shampoo with conditioner without the antibacterial agent triclosan that is commonly found in some soaps. It is a known carcinogen and many hunting type products have it in them. I get a really strange feeling on my skin when I use these products, kind of a clammy, smelly sweat...
For deodorant I use just unscented speed stick, it doesn't clump and fall off like the hunter brands, although I only use it during hunting season because again, the aluminum is known to cause alzheimer's disease.
With these few products, I know my scent volume is lowered, and I will wear the same undergarments without washing for several days on deer stands...and I put up and take down stands virtually every sit...unheard of with the hunting market products on every shelf. I notice a huge differene with my nose alone.
