The C-IN2 Prime Bi-Fly Brief reimagines a classic mid-rise silhouette with elevated construction and discreet innovation. Crafted from a soft, breathable cotton–lyocell blend, it delivers a smooth, lightweight feel designed for all-day ease.
A distinctive dual-functioning fly—accessible from either side of the pouch—adds everyday convenience without disrupting the clean lines of the brief. The partial 2-ply contour pouch provides gentle structure and support, while covered elastic leg openings ensure a secure, comfortable fit. Finished with C-IN2’s dynamic logo waistband, this is a modern essential defined by quiet detail and considered design.

Your mileage may vary, but these Prime briefs give me the best forward presentation of any underwear I’ve worn. The fabric used for the underwear is exceptionally soft and light, though the 1 inch waistband is a minor detriment some days.

The fly on this holds your junk a bit forward so makes things possibly appear larger? I like all my
Briefs from this company and have a rainbow of colors and styles in my underwear drawer. Consistently wears and washes well.
