In addition to making ultra-absorbent, anti-microbial, moisture-wicking and leak-resistant menstrual underwear, Thinx recently introduced a new product called 'Training Shorts.'
This new kind of fitness shorts is being branded as "period-proof," as they feature absorbent four-layer built-in underwear. The high demand for these Training Shorts by Thinx has reportedly created a 2,400-person waitlist, which can be attributed to the fact that the brand promises that these shorts can be worn in place of a tampon or sanitary pad when working out. As the brand describes, the shorts are meant to absorb sweat and "holds up to two tampons' worth" of blood.
The patented shorts also boast a range of features that make them ideal for workouts, and are available in sizes from XS to 3XL.
