Base Sport Legging in Black
We make things that work better and last longer. Our products solve real problems with clean design and honest materials.
Smooth, sculpted, and engineered down to the last seam. This legging features a bonded waistband for a soft-smoothing effect without added bulk, while a meticulously refined gusset and crotch construction creates a comfortable, considered fit through every movement. Bonded seams lie flat against the body without digging, and our custom spacer-lite fabric combines Lycra with soft yarns for flexible hold, zero sheerness, and a refined, silky feel. Minimally compressive and made for low-impact movement, it offers a gentle hug without restriction. Proof that the best support starts with a strong foundation.
