The brief that weighs almost nothing.
Low-slung, light, and barely on. The Flex Low Rise Brief pairs a clean, minimal cut with soft cotton-modal mesh — air in, weight out, support where you want it.
Fabric
57% Cotton, 38% Modal, 5% Elastane. Airy mesh knit with 4-way stretch — modal makes it softer than plain cotton, and the mesh keeps air moving against the skin.
Fit & Silhouette
Men's low-rise mesh brief — sits just below the natural waistline with a clean, streamlined profile.
Contour Pouch
2-ply contour pouch — sculpted support with natural lift.
Leg Bands
Smooth microfiber leg bands sit flat against the thigh — no digging, no ride-up.
Waistband
1.5" exposed elastic waistband with C-IN2 branding — soft hold, clean finish.
Fit note
True to size. For a looser fit, go one size up.
Care
Machine wash.
Imported.
Flex
Everyday basics in an airy cotton-modal mesh with 4-way stretch — softer than plain cotton, cooler than anything else in the drawer. Light layers for warm days and long ones.
Model's height is 6'1"/185 cm, and he is wearing size M.

Fit is perfect. Its true to size. The rise is not too low. The material is supportive while still showing a nice slightly forward bulge and some definition of what's in there.

These are not ‘low-rise briefs.’ I ordered my usual size and they fit like a tent. Going down a size would not help because they are cut so large. Disappointing.
