Effortless function, thoughtfully refined.

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.

    Review Date: 2025-01-21

    Customer Feedback:

    I had not had a bi-fly brief before and the sale price made their purchase worth trying. I like the design concept and appearance but the pouch runs larger than the Core and Hand-Me-Down lines which I normally wear. Therefore, these did not provide the support that like in a brief. The rest of the brief fit well and felt great. Too bad, really.
