Yoga leggings live or die on fabric hand-feel, recovery, opacity and colour consistency. For OEM buyers, the blend ratio is not trivia — it drives price, performance claims, lab tests and which certifications make sense. This guide compares nylon / spandex vs polyester / spandex for private label and OEM programs.
Nylon/spandex vs polyester/spandex
Nylon / spandex (polyamide / elastane) usually delivers superior recovery and a cool, slick hand — preferred for premium yoga and studio wear. Polyester / spandex costs less, dries fast, and suits entry price points or high-sweat training lines. Many brands run both: nylon for core black / navy heroes, polyester for fashion colour drops.
| Factor | Nylon / spandex | Polyester / spandex |
|---|---|---|
| Hand-feel | Cool, premium | Drier, sporty |
| Recovery | Typically stronger | Good if engineered |
| Cost | Higher | Lower |
| Quick-dry story | Good | Often stronger |
| Certification path | Often OEKO-TEX | OEKO-TEX / recycled stories |
Weight, opacity and squat testing
Most yoga leggings bulk between 220–280 gsm. Below ~240 gsm, squat-test opacity becomes a development priority — especially in light colours. Specify both fabric weight and finished-garment opacity approval before bulk. Agree lighting conditions for opacity checks so sample and bulk are judged the same way.
Development checklist for OEM buyers
- Define stretch direction (2-way vs 4-way) and recovery after wash cycles
- Align colour standards (Pantone / physical swatch) with ΔE tolerance
- Confirm brushed vs single-jersey for seasonal hand-feel
- Match waistband elastic width and modulus to brand silhouette
- Lock rise, inseam and size chart ownership before grading
Linking fabric to your SKU plan
Pick one hero nylon quality for core neutrals and one secondary polyester quality for colour fashion. Two bases simplify inventory and QC while still giving merchandising flexibility. Browse the yoga product library and yoga fabrics, or request fabric swatches.
How this connects to factory selection
Fabric capability is why “any activewear manufacturer” is a weak shortlist criterion. Ask whether the factory co-develops bases with mills or only cuts market stock. See also how to choose an activewear manufacturer and GOTS vs OEKO-TEX.
How buyers should spec nylon / spandex
Write the brief as a fabric decision, not a marketing adjective. For most premium yoga programmes the starting path is polyamide / elastane (nylon / spandex) on a named base:
- PowerForm™ 215 — structured squat-proof gate, the default nylon/spandex hero.
- AirTouch™ 195 — cooler / buttery studio hand on the same blend family.
- Heavier 260–280 gsm sculpting is not a named library base — it is a mill-development band. See the GSM guide. Do not confuse it with CloudTouch™ 260 (knit terry).

Named bases & Fabric Selector
For private-label speed, lock a published hand first: PowerForm™ 215 (structured, squat-proof gate) or AirTouch™ 195 (buttery / cool-touch). When GSM, feel and sustainability conflict, use the Fabric Selector — it recommends named bases or honest custom routes (e.g. ZS-ACT-250N66 at ~250 g/m²) without inventing compression grades.
