I love everything about this item but I wish the waist band was twice as thick to avoid curling. I think the waist band is 1 inch thick but maybe 2 inches would help. The pouch is a good size so I love that part and also the color is vibrant and very sexy. I bought a competing brand 1 week earlier and threw them away because quality was not as good as c-in2. I’ll keep these
Love the design
Love the design! This is my first thong purchased so I'm not sure if I got a size too big but the front pouch fit seems larger than I was expecting.
Great fit and very comfortable. Happy to have branched out from a typical jock.
I Love them
They look and feel great, nice fitting, i want more colors for this style,
Little tighter than expected

First pair. Nice fit. A little loose.
Y-back is simply the best
I purchased a y-back thong about a month ago, and I discovered a whole new side of the C-IN2 line that I’d never known about. I ordered three more thongs, including the Core Classic thong, the HARD/Core thong, and this one (Preston Pink Y-back), and I have to say that the y-back style is my favorite. They got everything right on this one. It’s so minimal, but so comfortable.
Great product, have had many Cin2 products in the past. Wished they would make the pouch out of a more breathable material, like Model, Silk, or mesh.
Fit well and feel great!
Sexy and Comfortable
Great product. Please design more products like this.
Love the Y-Back, Very Comfortable
The I decided to purchase this thong after buying the Scrimmage and Minimal thongs. This might be my new favorite. I definitely prefer the smaller elastic strap connecting the pouch to the waist band, it is more comfortable and less noticeable than a fabric strap. I went with a large because I own a couple low rise core briefs and those fit me well in that size. The only thing I noticed was the pouch is a little loose on the sides (otherwise 5 stars). The pouch did shrink a little after washing, but it still wasn't as supportive as the scrimmage jock and thong, minimal thong, or core briefs I own. I like the fabric of the Core range, but for the summertime the Scrimmage mesh can't be beat. If they made a Scrimmage thong with the Core style Y-back it would be my all-time favorite underwear. As always, these are the excellent quality I have come to expect from C-in2.
Fantastic fit and color!
Love these can’t stop buying
Bringing sexy back!
Great fit. The Hand Me Down line needs these.
best thong !!
Love the design.
Best thong ever
I am blown away how comfortable of a fit this product is. I finally found a thong that fits perfectly and the fabric breaths well. It’s so soft it’s like not wearing anything at all. Very sexy too!
