My wife's new favorite underwear for workouts
I purchased a pair for my wife to try before purchasing multiple pairs.
She says these are her new favorite for working out and runs. The construction is top notch. She says they are very comfortable and better than most g-strings and athletic underwear she has tried. We are both underwear aficionados, and we recognize that the quality exceeds other premier athleisure underwear brands. We will definitely be purchasing more. They truly are seamless and comfortable. No VPL whatsoever.
