Meet the Blackline Seamless Workout Set, squat-proof black leggings and a ribbed longline top, knitted seamless and woven on a loom in Brazil.

Zero transparency, zero chafing: a smooth, second-skin feel that moves from gym to street.

85% polyamide, 15% spandex. Designed in Austin, made for every role you play.

Engineered to sculpt

  • Seamless knit: no seams, no chafing, second-skin comfort

Absolutely obsessed with this set! The quality is truly next level, the fabric feels amazing, the fit is incredibly flattering, and everything stays comfortable and supportive without feeling restrictive. You can really tell how much thought went into the design and construction. I originally got it for workouts, but I’ve honestly been wearing it for everything. The fit is perfection and the quality really stands out. I already can’t wait to get it in more colors as soon as they become available!
