All the freedom, none of the lines.

There's a reason thong guys never go back. Nothing on the thigh, nothing on the cheeks, no lines under even your thinnest pants — just freedom you feel the second it's on.

C-Theory's version adds the color: a saturated body and a contrast band, for the few who get to see it.

Fabric
97% Cotton, 3% Elastane. Soft, breathable textured cotton you'll forget within the hour — light, stretchy, and nowhere it shouldn't be.

Fit & Silhouette
Men's low-rise cotton thong with a narrow back strap — minimal coverage and zero visible lines under anything.

Contour Pouch
Sculpted 1-ply contour pouch with center-seam construction — lift and definition right where you want eyes to land.

Leg Openings
Covered elastic openings sit flat against the skin — smooth, secure, nothing digging in.

Waistband
1.5" exposed elastic waistband with C-IN2 branding — the one piece of contrast on an otherwise bare canvas.

Fit note
True to size. For a looser fit, go one size up.

Care
Machine wash.
Imported.

C-Theory

Color theory you can wear — saturated cotton in one shade, contrast elastic in another, so every pair looks put together before you've put on anything else. Soft textured stretch makes it easy to wear every day; the color is why you'll want to.

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.
