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.

Packaging Disclaimer
We tried to do better for the planet, but this one didn't work out. To reduce our environmental impact, we packed select underwear styles in this collection in compostable bags. Some of these bags broke down sooner than we expected, so yours may arrive torn or damaged. We're sorry about that.
The underwear inside is brand new and unworn. If it's a gift, the bag may not be gift-ready. All other C-IN2 products are unaffected.
Model's height is 6'1"/185 cm, and he is wearing size M.

Love the elastic around the legs especially under the butt! Usually this area stretches out quickly but not these! Makes comfortable all day.
