One strap, zero lines — Y not?

The Y-back takes the thong one step further: a single elastic strap down the back, a sculpted pouch up front, and 100% cotton everywhere it touches. Barely there, completely comfortable — and nothing shows under anything.

Fabric
100% Cotton. Soft, breathable, and natural against the skin — the broken-in feel of a favorite tee, from the first wear.

Fit & Silhouette
Men's low-rise cotton Y-back thong — sits below the natural waist with a signature Y-back elastic strap and minimal coverage.

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

Leg Openings
Clean elastic binding sits flat against the skin — no digging, nothing to adjust.

Waistband
1.5" exposed elastic waistband with repeat C-IN2 branding — the frame on a minimal canvas.

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

Care
Machine wash.
Imported.

Core

Reviews Summary
Customers say these Y-back thongs are incredibly comfortable and feel like wearing nothing at all. The Y-back design is more comfortable than traditional thong styles, with many noting the thin strap is less invasive. Users love the ample pouch space and support, finding them perfect for daily wear, sports, and gym activities. The soft material washes well and maintains durability. Many customers become repeat buyers and recommend sizing up for the best fit, though some find them true to size. A few mention sizing inconsistencies between colors and note the fabric can feel slightly stiff initially.

    Perfect fitting pouch, the Y

    Perfect fitting pouch, the Y back is super comfortable, and they look great and feel wonderfully minimal in jeans and shorts. Will be buying more for sure.

    Great thong

    This thong fit exactly as expected. It is a little snug but I am really between sizes. I am not sure the ‘Y’ style is the best for me. I didn’t go with the medium only cause I don’t want to waste the money on something that was too loose. Overall an amazing product as always.

    Y-

    I bought the Y-Back thong for my husband. He tells me they are the most comfortable of all the thongs he owns. And I think the Y-back is somehow more sexy. My Mann has a great ass, and I like to see him wearing these underwear. I am concerned that you don’t seem to have any new thongs in the Y-Back style any longer. Will you have more in the future??
