Comfortable and a great fit.

Very comfortable and keeps the lines away when I need them. Would be great if they came in other colours other than black and blue!

Comfortable and breathable

The Kalenji running thong is so comfortable and breathable to wear. I had to get a dozen for myself. It stays in place when I run and do other sports and the fabric is soft and just comfortable. The design is also great as it has the right thong sizing, not a narrow thong and great for sports use. Also price wise, its good quality for the price.

Product testing

PERSPIRATION WICKING: the perspiration wicking test was conducted on each material in the laboratory to check that the fabric absorbs and transfers moisture from the inside of the fabric outward and eliminates it. WASHING: The washing and drying tests guarantee good stability (dimensional stability and color fastness) These tests are regularly conducted by an independent laboratory to confirm that our quality standards are applied.
