This is very concerning as this was not mentioned online when I purchased underwear. Apparently it is nanotechnology which is very dangerous to the human body. It bypasses the cell wall, the same way it works by inhibiting bacteria. The silver ions pass thru the cell wall of the bacteria. What is really concerning is the location of the nanoparticles in the genitalia region. Your reproductive organs are getting exposed continuously to these nanoparticles. I would NOT recommend this product.

[This review was collected as part of a promotion.] I have been looking all summer for a shirt I could wear for a undershirt that would not make me hot. These shirts fit the bill! I like the fact it does not add any extra warmth. They wash well. Only thing I would suggest is to order a size larger. They don't seem to be true to size. But great shirts.

[This review was collected as part of a promotion.] These are great T-shirts. They are very comfortable. The material is so soft. I also really love how they’re tag less. Tags really aggravate me. I always cut them off. With these you don’t have to do that. These T-shirts’ are perfect to just wear on their own or as under shirts. They are also very true to size.

[This review was collected as part of a promotion.] My husband says this undershirt is nice, soft cotton that feels good against the skin. It is a good quality cotton so it's not see thru like some undershirts around recently. It may be slightly smaller in the sleeve area, compared to other Hanes undershirts in the same size that we have owned. Washed up nicely.

[This review was collected as part of a promotion.] My husband loved these tees. The fit was perfect. He liked how the length was longer on these. The shirts were so soft and comfortable. These are a great shirt to layer with. Very happy and will definitely purchase in the future.

[This review was collected as part of a promotion.] The tee shirts look and feel extremely comfortable. Very well made and have the new option of helping with odor. I especially like that they are tagless which helps avoid any friction to the neck and upper body while working. I love Hanes prodycts and th

[This review was collected as part of a promotion.] Enjoyed the comfort of a nice soft T-shirt that was tag less. I’ve purchased competitor brands that still use a tag on the side seam. I find this tag to be itchy and scratchy. If I cut it out, then I have a hole in the side seam of my T-shirt. This Hanes T-shirt was soft and comfortable right out of the bag. Since it is short sleeved, I can wear it in the summer and then wear it layered as weather gets cooler. Good basic comfort in. T shirt. Recommend it.

I bought size Large -- I'm 5'11", 152. The shirts were tight (with very short sleeves) before washing. After washing & drying (very low, short time) they look like something a little boy would wear -- ridiculously small. Can't return, but won't buy again!

[This review was collected as part of a promotion.] These tees are great for my son to wear to bed. They are on the soft side and of course tagless so they are perfect to sleep in for him. Receives all black and they are spot on. Hanes has become a staple in our home!!

[This review was collected as part of a promotion.] Hanes has done it again! The tagless tshirts are so soft and comfy and you never have to worry again about the bothersome tags. Just wear it and go. The only thing you’ll think about is how comfortable you are in it.
