MU StarAir トレーニングショーツ（裏地付き） - ブラック

The built-in lining really makes a difference—I don't have to worry about see-through issues during squats or lunges, and the fit stays put through my whole workout.

I’ve been wearing these to the gym for a week now, and the built-in lining stays put during squats without riding up. The fabric feels surprisingly breathable, even during a long cardio session. Exactly what I needed for versatile training wear.

The built-in lining is a game-changer—no more worrying about riding up during squats. The material feels breathable and moves well through a full workout.
