Olaf Benz included a yellow ribbed swim thong in their 2024 collection, but it’s no longer available. Charlie by MZ also used to offer ribbed swim thongs in several colors, including yellow. I had one in olive green, but the fabric didn’t hold up as well as other materials.
Thanks for the mention of AWRY. Just received a 3-pack of their PULSE V-string. These are the perfect thong, in my opinion! Next order will be in the ribbed fabric.
