I love that the core thongs are GOTS organic. They are comfortable and very breathable. On the downside, I had issues with the stitching of the core thongs coming apart. Victoria with Organics Basics was very quick to assist me with my issue, as well as very pleasant and professional, and is sending me replacements for the thongs for which I had issues. Customer service is very good with this company and I would be willing try out their other products. Five stars for the GOTS organic certification and the customer service.
