These Briefs are done up in a soft microfiber fabric, but don't let that fool you into thinking this is a classic brief! Instead we've taken the sides away completely for a sexy glimpse of skin, and joined the front panel to the back with straps for the ultimate sexy brief. Contour pouch offers lift and definition. 93% Nylon 7% Spandex. Wash Separately, Drip Dry, do not Bleach.
