Unique Y-Back Thong in Vintage Cotton Design

Old-school gym energy in a sexy Y-back thong. The Throwback Y-Back Thong is the pair you put on when you already know how the night ends — soft cotton jersey against skin, white ribbed trim tracing every edge, and a back that's built to be looked at.

From the front it's clean and sculpted. From behind, two straps run up to the waistband and leave everything between them bare.

Fit & Silhouette
Men's low-rise cotton Y-back thong — minimal front coverage and an open back, cut close enough that nothing shifts and nothing shows through slim denim.

Y-Back Construction
Two straps run wide across the hips and meet the center strap below, leaving open space on either side. Less fabric, more frame — and the wide set means nothing digs in.

Soft Single Knit Jersey
95% Cotton, 5% Elastane. Lightweight single knit that feels broken-in from the first wear, with just enough stretch to move when you do.

Contour Pouch
1-ply contour construction shapes and lifts with a single layer of jersey. Natural definition — no padding, no bulk, nothing to adjust.

Rise
Low-rise, sitting below the natural waist so the logo band is the first thing that shows when your jeans sit low.

Binding & Trim
White ribbed binding outlines every edge in contrast, pulling the eye along the cut and giving the whole pair its locker-room-era finish.

Waistband
1.25" elastic waistband with the C-IN2 logo repeated across a striped retro edge — the detail that reads instantly, even from across the room.

Fit note
True to size. For looser fit, size up.

Care
Machine wash.
Imported.

Throwback

Throwback runs on gym-locker nostalgia — single knit jersey, contrast ribbed binding, and a logo band lifted straight out of a 1970s catalog. Classic silhouettes, current fits.
