Product title: Andrew Christian Men's Almost Naked Brief W/Show It
Product description: A classic sexy piece in all new colors! we've kept it straight forward with the almost naked brief with show-it technology, and have brought it back in all new colors. Each pair features bright colored contrast trim at each leg and around the front pouch. It offers a hidden comfy cup that gently lifts and provides excellent frontal support and enhancement. This horseshoe shaped inner cup is lined by soft elastic and adds up to 1.5 inches (3.8 cm) to a man's frontal measurement and provides the biggest natural enhancement of any underwear in our line. When you pull them on, your package falls naturally into the super soft snuggle pocket to create a truly enjoyable unique wearing experience.
