Your fabric choice is the single most important decision in activewear manufacturing. It determines how your garment performs, how it feels on the skin, how long it lasts, and—ultimately—how customers perceive your brand.
But with dozens of fabric options, blends, weights, and finishes available, choosing the right one can be overwhelming.
This guide breaks down the most common activewear fabrics, their properties, and the best applications for each, helping you make informed decisions for your yoga wear, sportswear, and outdoor gear lines.
The Three Core Fibers
All performance activewear is built from three primary fibers combined in different ratios:
Nylon (Polyamide)
The premium choice for high-end activewear.
| Property | Rating |
|---|---|
| Stretch Recovery | ★★★★★ |
| Softness / Hand Feel | ★★★★★ |
| Color Vibrancy | ★★★★★ |
| Durability | ★★★★☆ |
| Moisture Wicking | ★★★★☆ |
| Cost | Higher |
Nylon has better stretch recovery and a softer hand feel than polyester, making it the preferred fabric for yoga wear and premium leggings. It holds dye exceptionally well, producing richer, deeper colors.
Best for: Yoga leggings, sports bras, compression wear, high-end activewear
Common blend: 80% Nylon / 20% Spandex (the “gold standard” for leggings)
Polyester
The workhorse of performance fabrics.
| Property | Rating |
|---|---|
| Stretch Recovery | ★★★☆☆ |
| Softness / Hand Feel | ★★★☆☆ |
| Color Vibrancy | ★★★★☆ |
| Durability | ★★★★★ |
| Moisture Wicking | ★★★★★ |
| Cost | Lower |
Polyester excels at moisture management—it’s more hydrophobic than nylon, meaning it moves sweat away from the body faster. It’s also more UV-resistant and typically less expensive.
Best for: Running wear, team uniforms, hiking gear, outerwear, budget-friendly activewear
Common blend: 85% Polyester / 15% Spandex
Spandex (Elastane / Lycra)
The magic ingredient that gives activewear its stretch.
Spandex is never used alone—it’s blended with nylon or polyester at ratios of 5-30%. The spandex percentage determines how much stretch and recovery the fabric has:
| Spandex % | Stretch Level | Best For |
|---|---|---|
| 5-10% | Light stretch | Outerwear, jackets, loose-fit tops |
| 10-15% | Moderate stretch | Running tights, casual leggings, tank tops |
| 15-20% | High stretch | Yoga leggings, sports bras, compression wear |
| 20-30% | Maximum stretch | Dancewear, high-intensity sports bras |
For yoga wear, 18-22% spandex is the sweet spot—enough stretch for full range of motion, with excellent recovery so the garment doesn’t sag.
Fabric Weights (GSM)
GSM (Grams per Square Meter) measures fabric density. The right weight depends on your garment’s intended use.
| Weight Range | Description | Best For |
|---|---|---|
| 120-150 GSM | Lightweight, semi-sheer | Tanks, t-shirts, summer layers |
| 150-180 GSM | Light-to-mid weight | Running tops, yoga tanks, sleeveless garments |
| 180-220 GSM | Mid weight (sweet spot for leggings) | Yoga leggings, sports bras, fitted tops |
| 220-280 GSM | Mid-to-heavy weight | Running tights, compression gear, joggers |
| 280-350 GSM | Heavy weight | Outdoor pants, hiking gear, winter activewear |
Most premium yoga leggings use 180-220 GSM nylon-spandex. Go heavier (220-280 GSM) for hiking pants and outdoor gear where abrasion resistance matters more.
Fabric-by-Application Guide
For Yoga Wear
| Requirement | Recommended |
|---|---|
| Primary fiber | Nylon (better stretch recovery for poses) |
| Spandex content | 18-22% |
| GSM | 180-220 |
| Finish | Matte, brushed for opacity |
| Key properties | 4-way stretch, opaque on squat test, soft hand feel |
Yoga demands maximum stretch recovery because you’re constantly moving between poses. Nylon-spandex with matte finish is the industry standard for premium yoga leggings.

For Running & Training
| Requirement | Recommended |
|---|---|
| Primary fiber | Polyester (better moisture management) |
| Spandex content | 12-18% |
| GSM | 180-250 |
| Finish | Smooth, moisture-wicking |
| Key properties | Quick-dry, lightweight, flatlock seams to prevent chafing |
Polyester’s moisture-wicking properties make it ideal for high-sweat activities. Look for fabrics with a brushed inner surface for comfort or smooth outer surface for aerodynamics.
For Outdoor & Hiking Gear
| Requirement | Recommended |
|---|---|
| Primary fiber | Polyester or nylon blend |
| Spandex content | 5-15% |
| GSM | 220-350 |
| Finish | DWR (Durable Water Repellent) coating or bonded fleece backing |
| Key properties | UV resistance, abrasion resistance, wind resistance, quick-dry |
Outdoor gear needs to perform in variable conditions. Heavier weights, reinforced seams, and technical finishes (waterproof, windproof, insulated) are common requirements.

For Sports Bras
| Requirement | Recommended |
|---|---|
| Primary fiber | Nylon or polyester |
| Spandex content | 15-25% |
| GSM | 200-280 |
| Key properties | High compression, moisture management, stable straps, soft inner lining |
Sports bras require more spandex for compression, especially for high-impact styles. The fabric must hold tension without losing recovery over time.
Specialized Fabric Types
Recycled Fabrics (GRS Certified)
Made from post-consumer or post-industrial waste (plastic bottles, fishing nets, fabric scraps). Increasingly demanded by eco-conscious brands.
- Recycled Polyester (rPET): Made from PET bottles. Performance comparable to virgin polyester.
- Recycled Nylon (ECONYL): Made from regenerated nylon waste (carpets, fishing nets). Identical performance to virgin nylon.
Premium customers are willing to pay 15-25% more for sustainable activewear. Offering a GRS-certified option differentiates your brand.
Supplex / Tactel
Branded nylon variants that feel like cotton but perform like performance fabric. Popular for lifestyle-activewear crossover styles.
Meryl
Another branded nylon with silky hand feel and excellent moisture management.
Brushed Fleece / French Terry
For outerwear layers—quarter-zips, hoodies, joggers. Not for high-performance yoga but ideal for athleisure and layering.
Mesh
Used for ventilation panels in sports bras, running shirts, and shorts. Typically polyester-based for maximum breathability.
Common Fabric Problems and How to Avoid Them
| Problem | Cause | Solution |
|---|---|---|
| Sheer / squat-proof failure | Too low GSM or too high spandex | Use 180+ GSM, test stretch on dark colors |
| Pilling | Low-quality fiber, poor twist | Specify high-twist nylon, test for Martindale abrasion |
| Color fading | Poor dye quality, low UV resistance | OEKO-TEX certified dyes, polyester for outdoor wear |
| Seam puckering | Wrong needle/thread for stretch fabric | Use ballpoint needles, stretch thread, coverstitch seams |
| Fabric snagging | Loose knit structure | Specify tighter knit construction, higher denier yarns |
| Loss of shape | Too little spandex or poor recovery | Minimum 15% spandex for fitted garments, test recovery after 20 washes |
How to Specify Fabric to a Manufacturer
When requesting a quote from an activewear manufacturer, include these fabric specifications:
- Fiber composition (e.g., 80% Nylon / 20% Spandex)
- Yarn type (e.g., 40D/70D — denier = filament thickness)
- GSM weight (e.g., 200 GSM ±5%)
- Construction (e.g., 4-way stretch single jersey)
- Finish (e.g., matte, brushed, anti-microbial, moisture-wicking)
- Certification (e.g., OEKO-TEX Standard 100)
- Color (Pantone code or lab dip reference)
