Customer Feedback:
I absolutely love C-Theory! The fit is perfect and holds my not-so-small package comfortably. The fabric is very soft and feels great to wear. I definitely recommend it to anyone, whether you have a smaller or larger package. Every color is just as comfortable — whether it’s green, navy, or orange. I ended up buying all three!
