Made from premium Lenzing™ Modal rib fabric, this thong delivers a soft, breathable, melt to the skin feel with natural stretch that moves with you. The ribbed texture gently contours your shape, offering light support while maintaining a relaxed, breathable space where you need it most.

Nice, soft, thin, minimal thong. Perfect fit and rise. Fits true to size for me.

The fit is smaller and tighter than the modal bikini thong. I would recommend sizing up.

wish it had more stretch and recovery

I bought two of these - they are great when you first put them on. But they stretch out during the day and don't have any elastic fabric component to help them return to their normal shape. By the end of the day they are just too loose for my taste. If wearing for a short time, great! And day wear - not so sure.

Pouch is a little small

I own several JA thongs and the rib modal one has a very small pouch. If you are average or above, there is little chance you can keep “everything” inside. I like the feel the fabric is nice, just needs more space in the pouch.

First Thong

I am 5’10”, 170lbs, 32in. waist and ordered a medium. I think it fits well, though this is my first thong. Very soft and comfortable in the front. Maybe this is the case with all thongs, but my only complaint is a seam that separates the front from the back. After a few hours the seam starts to rub a little. Otherwise very nice.
