NILO by Jersey Lomellina® – The Italian Stretch Fabric Redefining Premium Activewear

Reading time: ~7 minutes


If you've ever worn leggings or activewear that truly felt like a second skin — smooth, supportive, breathable, and lightweight — then you've already experienced the difference between ordinary stretch fabric and premium technical textiles.

But finding all of those qualities in a single fabric, while also offering chlorine resistance, fast drying, elegant drape, and genuine Italian production quality, is rare.

This is where NILO by Jersey Lomellina® stands apart.

Produced in Italy by one of Europe's most respected technical textile mills, NILO combines refined aesthetics with real performance functionality. It is increasingly becoming the preferred choice for:

  • Premium activewear brands
  • Swimwear designers
  • Athleisure collections
  • Independent makers and MYOG projects
  • Technical fashion garments

In this review, we'll break down:

  • What NILO actually is
  • Why polyamide outperforms many polyester blends
  • How it compares to other stretch fabrics
  • What projects it works best for
  • Why Italian textile production still matters

What Is NILO by Jersey Lomellina®?

NILO is a lightweight premium stretch fabric produced by Jersey Lomellina®, an Italian textile mill specializing in high-end technical fabrics for activewear, swimwear, and sports fashion.

The fabric is constructed from:

Composition 86% Polyamide (PA) / 14% Elastane (EA)
Weight ~120 g/m²
Width ~140 cm
Origin Made in Italy
Stretch Type Two-way stretch
Finish Matte, smooth, silky surface

The result is a fabric that sits perfectly between technical sportswear and refined fashion textiles.


Why Polyamide Performs Differently

Polyamide (Nylon) – The Technical Foundation

At 86% polyamide, NILO gains many of the properties that define premium performance fabrics.

Key Advantages of Polyamide

  • Excellent durability – highly resistant to abrasion and repeated stretching
  • Lightweight structure – strong without feeling heavy
  • Silky skin feel – softer and smoother than most polyester fabrics
  • Premium matte appearance – refined visual texture without excessive shine
  • Better chlorine resistance – ideal for swimwear and pool environments
  • Quick drying – helps regulate comfort during movement

Compared to lower-cost polyester activewear fabrics, polyamide generally feels more luxurious against skin and maintains its appearance longer under repeated use.


14% Elastane – Stretch With Recovery

The elastane content is where NILO achieves its movement performance.

At 14% elastane, the fabric delivers:

  • Smooth stretch recovery
  • Freedom of movement
  • Gentle compression
  • Shape retention
  • Comfort without excessive tightness

This percentage places NILO in an ideal middle ground:

Fabric Type Typical Elastane % Stretch Category
Basic jersey 2–5% Light stretch
Standard activewear 8–12% Two-way stretch
NILO by Jersey Lomellina® 14% Enhanced two-way stretch
Compression sportswear 18–25% High compression
Competition swimwear 15–20% Four-way stretch

NILO offers enough elasticity for technical movement while maintaining a refined and elegant hand feel.


NILO vs Other Stretch Performance Fabrics

NILO vs Polyester/Elastane Fabrics

Most mass-market activewear uses polyester/elastane blends due to lower manufacturing cost.

Property Polyester Blend NILO (Polyamide Blend)
Skin feel Can feel synthetic Silky and smooth
Chlorine resistance Moderate Excellent
Visual finish Often shiny Refined matte
Comfort Good Premium
Durability Good Excellent
Origin Usually mass-produced Made in Italy

For low-cost gym apparel, polyester blends are sufficient. For premium activewear, swimwear, or garments worn directly against skin, polyamide fabrics typically offer a superior experience.


NILO vs Econyl®

Econyl® is a regenerated recycled polyamide often used in sustainable swimwear.

Property Econyl® NILO
Sustainability focus Very high Performance-focused
Surface softness Good Superior
Hand feel Slightly technical Smoother and softer
Best use Eco swimwear Premium activewear & lining

NILO vs Supplex®

Supplex® fabrics are designed to imitate cotton while maintaining synthetic performance properties.

Property Supplex® NILO
Feel Cotton-like Smooth and silky
Weight Usually heavier Lightweight
Appearance Casual matte Technical refined matte
Best use Yoga & casual wear Technical activewear

Best Uses for NILO

Activewear Leggings and Tops

At 120 g/m², NILO remains lightweight during movement while still offering enough structure for support and coverage.

  • Gym apparel
  • Running tights
  • Yoga wear
  • Pilates clothing
  • Training tops

Swimwear Lining

This is one of the strongest applications for NILO.

The chlorine resistance, quick-dry performance, and smooth skin feel make it ideal for:

  • Bikini lining
  • One-piece swimsuit lining
  • Swim shorts lining
  • Technical swimwear interiors

Compression and Recovery Apparel

NILO provides light-to-moderate compression without feeling restrictive.

Suitable applications include:

  • Compression shorts
  • Training sleeves
  • Recovery garments
  • Performance base layers

Athleisure and Technical Fashion

The refined matte appearance allows NILO to transition naturally between sportswear and everyday fashion.

The fabric photographs exceptionally well under studio lighting and maintains elegant drape characteristics rarely found in lightweight technical fabrics.


Why Made in Italy Still Matters

Italy remains one of the world's most respected regions for technical textile manufacturing.

Jersey Lomellina operates within a textile ecosystem known for:

  • Advanced knitting technology
  • Precise finishing processes
  • Consistent dyeing quality
  • Reliable stretch recovery
  • Strict quality control standards

For designers and brands, this translates into real-world advantages:

  • Consistent color across rolls
  • Predictable cutting and sewing behavior
  • Professional finish quality
  • Reliable production repeatability

Sewing Notes

Because NILO is a polyamide/elastane performance knit, proper sewing setup is important.

Recommended:

  • Ballpoint or stretch needle
  • Polyester thread
  • Overlock, coverstitch, or narrow zigzag stitch
  • Stretch-compatible seam construction

A standard straight stitch may break under tension during wear.
