14 Best Black Leggings, According to Glamour Editors and Reviewers

• Sizing: We sought out brands that are size-inclusive, with options that go up to at least XL (plenty of our picks go up to 4XL). We picked petite and tall-friendly options with a range of waist and inseam sizes.
• Material: We looked for leggings made of high-quality and durability fabrics with moisture-wicking qualities, breathability, softness, and necessary compression. We considered which materials would be best suited for different fitness activities: Natural fabrics (like cotton) tend to be more sustainable and breathable, while synthetic fabrics (like nylon and polyester) are better for moisture-wicking.
• Style: Function is important, but we also took style into account, such as color, pattern, and overall aesthetic appeal.
• Pilling/Fading: We monitored how well the leggings stood up to a minimum of five wears and washes, noting pilling and fabric degradation.
• Fit and Design: We sought out leggings that were well-designed, fit comfortably on the body, and included innovative features (like pockets or strategic mesh panels).
• Slip and Squat Test: All leggings passed the “slip test,” meaning they didn’t slip, slide, or roll down during workouts. They also passed the “squat test,” meaning the fabric didn’t become transparent while squatting.

To determine which black leggings were truly the “best,” our testers wore (and washed) each pair a minimum of five times, during various types of activity (running, hiking, lounging, running errands, and more). Based on firsthand experience, testers determined which pairs excelled in every category of criteria (fit, sizing, material, etc.) From there, our team narrowed down the best pairs to suit various needs and preferences. We also noted which ones held up to regular wear and washing (meaning how much the fabric thinned or pilled).
