Custom Gym Wear Manufacturing: Complete Guide for Fitness Brands and Gyms

<p>A streetwear founder messaged me on LinkedIn last month asking about custom gym wear manufacturing: complete guide for fitness brands and gyms. The answer I sent her was three paragraphs long and covered most of what I'd say to anyone. This article is the longer version, with the production-floor details I didn't fit into the DM.</p># Custom Gym Wear Manufacturing: Complete Guide for Fitness Brands

The global gym wear market is projected to REACH $289 billion by 2027. Driven by the athleisure trend and growing health consciousness, custom gym wear represents a lucrative opportunity for fitness brands, gyms, and apparel entrepreneurs.

Fabric Guide for Gym Wear

Nylon-Spandex (Polyamide-Elastane)

The premium choice for leggings and sports bras. 80% nylon, 20% spandex is the most popular ratio.

Properties: Exceptional softness, superior stretch and recovery, chlorine-resistant, fade-resistant, good opacity.

Weight: 180-260 GSM. Heavier = more supportive and less see-through.

Best for: Premium leggings, sports bras, bike shorts.

Polyester-Spandex

Most popular fabric for all-around gym wear. 88% polyester, 12% spandex.

Properties: Moisture-wicking, quick-drying, good stretch, more affordable than nylon-spandex.

Weight: 150-220 GSM.

Best for: Training shorts, tanks, jerseys, mid-range leggings.

Performance Mesh

100% polyester or nylon mesh. Highly breathable. Often used as a panel insert rather than the primary fabric.

Best for: Back panels, pocket linings, ventilation zOnes.

The Squat Test: What It's and Why It Matters

Every gym legging must pass the squat test, when squatted, the fabric should remain fully opaque and not become see-through. To achieve squat-proof construction:

1. Use minimum 200 GSM fabric (higher for darker colors)

2. Include a full internal lining panel in the gusset area

3. Use nylon-spandex rather than polyester-spandex (better opacity)

4. Test samples rigorously before bulk production

Customization Options for Gym Wear

All-Over Sublimation: Full-color, all-over pattern printing. Only works on polyester. Ideal for bold brand-differentiated designs.

Heat Transfer Vinyl (HTV): Solid-color design transfer. Good for logos and text on polyester or nylon fabrics.

Embroidery: Premium for logos, but limited on stretch fabrics due to stiffness. Works best on waistbands and non-stretch areas.

Custom Waistbands: Branded elastic waistbands are a signature of premium gym wear brands.

Custom Labels: Woven or print labels with your brand name, care instructions, and size.
