Male Power doesn’t always make super sexy underwear. They have been known to make some great underwear you could wear to the gym. The Bamboo line is one that comes to mind that did very well for them. The newest line is the Rayon Swag line. It gives you the feel of silk without the price of silk!
Here is the write up from Male Power:
Men who like the look and feel of silk, but not the cost, will really enjoy the Rayon Swag collection from Male Power.
Rayon, nylon and spandex combine to create highly attractive undergarments that are sensationally soft and stretchable. The fabric, in either black or taupe, contains a subtle texture and a hint of sheen. Rayon Swag comes in five classic styles, including racer back tank top, mini short, wonder bikini, wonder thong and posing strap.
The classically styled wonder bikini and thong offer full, round uplift pouches. The mini short pairs perfectly with the tank top. None of the garments contain any exposed elastic.
