I'm a little center of left from you on this, I think and my personal anecdotal evidence suggests some of this stuff has value. Especially the spray which I whip up as a home brew for $4 per gallon

I've gotten away with stuff I never did in the past, enough to give me some confidence in it.

I guess the allure of having scent absorption is the icing on the cake. I agree that apparently bacteria can't reproduce in the presence of silver, but even if what the manufacturers state is true, that it's good "for the life of the garment", logic suggest the stuff would have to be in constant contact with your skin, where the little nasties live. Hard to do in the pits, crotch and under a full head of hair .

As for the ab-scent, it's been around for years, doesn't seem to have caught on, either bad marketing or it doesn't work.

The no-trace sounds intriguing, and again is reported to outlast the garment, but they want just a hair under what carbon goes for, basically for soaking some camo clothes in a vat of the stuff

If it was a liner type system made of a wicking material and went for around $20 per pant and shirt and headnet, I'd try it. Apparently though, the company has allusions of granduer. Perhaps they wanna make a killing before people like you catch on and wise the rest of us up...
