Because we often need yoga at the busiest, most stressful times in our lives, we designed the Nike x MMW Top to be the most efficient yoga mid-layer on the market. We partnered with fashion designer Matthew M. Williams to give it a look you'll feel confident wearing on and off the mat. Its engineered knit construction feels cozy under your favorite puffer jacket while mesh panels help heat escape to keep you cool throughout your session. This product is made with at least 75% recycled polyester and recycled nylon fibers.
