Our top selling style is the classic C-IN2 Low No Show Profile Brief 1713.  C-IN2 is also known for it’s sling support technology designed to give you a more enhanced profile.  A ½” wide elastic sling inside the pouch forms a ring around your genitals and lifts them forward for a more pronounced look.  Most customers find it perfect for wearing with low rise jeans.
