I'm not sure, I hope they are the same as my previous ones that were from Jockey. I hope the fabric isn't too thin when they arrive as they don't tend to last with too thin material. Also, they don't absorb sweat when the material is too thin.
A. It was in a size that would fit me. B. I live in a warm climate and prefer minimal amounts of clothing. I would buy other styles if they were available in my size such as string bikinis. C. There was a (minimal) choice of colors.
The contrast and design in colors initially caught my attention. The cut and coverage of the brief is moderate which is a plus as I steer more towards a bikini brief for support, style, but above all, comfort.
