I looked at the tag and saw that these were a combination of cotton, micro modal, and spandex. It gives these shorts a very different feel from the other pairs I have. They feel very soft (not quite as soft as pure micro modal), and they feel very snug (but not restrictive). I feel like they give extra support in the crotch (they made my bulge look smaller, which can be a good or bad thing). The slight shine is also attractive - makes them look expensive. I would definitely get another pair with this material.
The waistband is interesting for two reasons: The low-rise cut and the shiny silver fabric. I know that a lot of people asked for low-rise underwear in your reviews online. I did not really like the low-rise cut when I first tried it on (kept trying to pull it up), but as I got used to it I realized that it made these underwear much sexier than the other pairs. My wife said they look attractive on me. I think it is a good addition, but I would like to see it as optional (not everyone will want that style). The silver waistband was surprising, and again I was not sure how I liked it, but now it has grown on me and I think it makes these underwear look very special. I do like it.
Just so you know - my wife is very jealous of me for having such great fabric and construction in my underwear! She asked me whether you made underwear for women! :)
