Nylon vs. Polyester: Which Fabric Should Your Yoga Leggings Be Made Of?
Nylon and polyester dominate activewear fabric sourcing — but they behave very differently. Here is how to choose the right one for your yoga legging line based on feel, durability, cost and target market.
Nylon and polyester are the two fabrics behind almost every pair of yoga leggings on the market — and they are not interchangeable. The choice affects how your product feels, how it wears, how it dyes, and what margin you can hold. Here is a practical breakdown for buyers and brand owners.
Quick Comparison
| Property | Nylon (PA) | Polyester (PET) |
|---|---|---|
| Hand feel | Softer, silkier, more “naked” | Firmer, more structured |
| Stretch & recovery | Excellent with spandex | Good, slightly less elastic |
| Moisture wicking | Fast | Very fast, dries quicker |
| Durability | High abrasion resistance | High, resists UV better |
| Cost | Higher | Lower |
| Best for | Premium leggings, seamless, brushed styles | High-volume sportswear, sublimated prints |
When to Choose Nylon
Choose nylon (usually nylon 6 or nylon 66 blended with 20–28% spandex) when you are targeting the premium end of the market:
- Buttery, brushed, “bare-feel” leggings
- Seamless knit construction
- Squat-proof four-way stretch requirements
- Skin-friendly claims for everyday wear
The trade-off is cost — nylon typically runs 20–40% higher than polyester at the fabric stage. Most premium yoga brands accept this because the feel is the product.
When to Choose Polyester
Polyester (often 88% polyester / 12% spandex) is the workhorse of high-volume activewear:
- Performance and training lines where durability wins
- Sublimation-printed designs (polyester takes dye sublimation beautifully)
- Outdoor and UV-exposed products
- Price-sensitive markets and large repeat orders
What About Blends and GSM?
Most real-world yoga leggings sit between 220 and 280 GSM. Under 200 GSM feels thin and risks opacity; over 300 GSM feels bulky and slows dry time. Ask your factory for a GSM swatch card before committing — the number on a spec sheet rarely matches the hand feel.
How to Decide: A Three-Question Test
- Who is the customer? Premium boutique → nylon. Volume sportswear → polyester.
- Is there a print? Complex sublimated graphics → polyester.
- What is the target retail price? If landed cost must stay under ~$6/pair, polyester is usually the only way.
