The fabric your leggings are made of determines everything. How they feel against your skin, how well they manage sweat, how long they hold their shape, and whether they go see through the moment you squat. It's the single most important factor in legging quality, and most people never think to check it. The secret to the Diva Goddess fit is our signature blend. By using a high-density, moisture-wicking material in our compression leggings collection, we ensure a breathable fit that provides maximum lift and support.
Here's a breakdown of the most common legging fabrics, what each one does well, and what to look for when you shop.
The Best Fabrics for Leggings
Nylon Spandex | The Gold Standard
Nylon spandex blends are the top choice for performance leggings. Nylon is durable, smooth, and naturally moisture-wicking. Spandex (also called elastane or Lycra) provides the four-way stretch that allows a full range of motion without the fabric losing its shape.
A nylon spandex blend typically runs 75 to 85% nylon and 15 to 25% spandex. This ratio gives you a fabric that's thick enough to be fully opaque, stretchy enough to move freely, and durable enough to hold its shape through hundreds of washes.
This is the fabric blend used in the Sculpt & Empower Leggings and Power Leggings, and it's why they perform the way they do.
Polyester Spandex | A Solid Alternative
Polyester spandex blends are the most common fabric in mid-range leggings. Polyester is lightweight, quick drying, and holds color well. It's a solid performer for lower intensity workouts, but doesn't match nylon for softness, durability, or moisture management over time.
Polyester tends to pill faster than nylon and can feel slightly rougher against the skin. For everyday wear and lighter workouts, it's a reasonable choice. For high-output training, nylon is the better investment.
Cotton Blends | For Casual Wear Only
Cotton leggings have no place in a serious workout wardrobe. Cotton absorbs moisture and holds onto it, which means you'll feel wet, heavy, and cold within minutes of starting any real training session. Cotton also loses its shape quickly and doesn't provide the compression or support that performance leggings require.
Save cotton leggings for lounging. For anything active, choose a performance fabric blend.
What the Spandex Percentage Means
The spandex percentage in your leggings determines how much stretch and recovery you get. Here's a general guide:
- 10 to 15% spandex, light stretch, more structured feel, better for yoga and low-impact activities.
- 20 to 25% spandex, high stretch, excellent recovery, ideal for high-impact training and strength work.
- Above 25% spandex, very stretchy but may sacrifice opacity and durability over time.
What to Look for on the Label
When shopping for leggings, check the fabric composition label before anything else. Here's what to look for:
- Nylon content above 70%, the higher the nylon, the more durable and smooth the fabric.
- Spandex between 15 and 25% the sweet spot for stretch, recovery, and opacity.
- No cotton, for any workout leggings, cotton is a dealbreaker.
- Four-way stretch confirms the fabric moves in all directions without resistance.
Why Fabric Affects Fit and Longevity
High-quality fabric holds its shape wash after wash. Low-quality fabric stretches out, loses compression, and starts to sag in the seat and knees after just a few months of regular wear. The fabric composition is the single biggest predictor of how long your leggings will last and how good they'll look while they do.
The Motion Flex Leggings and Glow Leggings are both built with premium fabric blends that maintain their shape, compression, and opacity through consistent training and regular washing.
The Bottom Line
The best legging fabric is a nylon spandex blend with at least 70% nylon and 15 to 25% spandex. It's the combination that delivers the best performance, the longest lifespan, and the most comfortable feel against your skin.
