Sleek, minimal, and cut to move.

The C-IN2 Prime Sport Brief brings a refined edge to a bold, athletic silhouette. Designed with a high-cut leg and low-profile shape, it offers greater freedom through the thigh while maintaining a clean, tailored look.

Crafted from an ultra-soft cotton–lyocell blend, this brief delivers breathable comfort with a smooth, elevated feel. A 2-ply contour pouch provides sculpted support and structure, while covered elastic leg openings ensure a secure fit that moves naturally with the body. Finished with C-IN2’s dynamic logo waistband, this is modern underwear—precise, confident, and made to be worn.

Fit Note: Runs small. We recommend sizing up (if you usually wear a size M, order a size L).
