Warning - contains anti-microbial additive (embedded nanosilver particles)
I was really excited about ordering these shirts after much research, only to be sorely disappointed when they arrived in the mail.
My primary concern is their "Dual Defense" additives, specifically IntelliFresh, which refers to DuPont's SILVADUR embedded nanosilver particles. This is not mentioned *ANYWHERE* in Amazon's product description or photos, so I thought it was worth posting a review for others to be aware. I have included photos of the packaging so you can see what I mean.
What's so bad about nanosilver? Isn't odor-fighting, moisture wicking technology a good thing?!
I used to think so, but now don't anymore. I encourage you to do your own research, but the latest info says it is best to avoid antimicrobials completely because they provide no net benefit to humans and many of them are suspected endocrine-disruptors. Nanosilver is relatively new and not well-researched compared to traditional silver, but it can pass the blood-brain barrier and if ingested could interfere with your healthy gut bacteria.
Additionally, silver is extremely toxic to marine life (second only to mercury), and when these particles wash out of your clothes in the laundry, they will eventually end up either in the ocean/rivers, or in wastewater treatment plant sludge, which is often land-applied as fertilizer. This could do massive harm to ecosystems.
If you want to learn more, search online for the "six classes of chemicals" website and then go to the section on Antimicrobials. The Resources section at the bottom of the page has links to lots of useful info, including:
--"Silver Nanotechnology and the Environment: Old Problems or New Challenges," Pew Project on Emerging Nanotechnologies report, 2008
--"Some antibacterials come with worrisome silver lining." Chicago Tribune, 2/16/2014
--"Germ-resistant clothes: pick or pass?" ABC News, 3/11/2012
I have no affiliation with that website; a coworker shared it with me recently which triggered me to research more on my own.
I returned the undershirts to Amazon immediately and did not open the package, so I can't speak to their fit or durability. I suspect they are great shirts except for the nanosilver additive, which makes this all the more disappointing.
Fruit of the Loom, if you're reading this, please offer these exact same shirts but in plain old cotton (no additives)! I would happily pay for that.
