Fabric Selection Guide for Clothing Manufacturing
đź“‹ Key Takeaways
- GSM determines fabric weight—choose based on garment type and season
- Cotton blends offer the best balance of comfort and durability for streetwear
- Fabric cost varies significantly: cotton $3-8/kg, polyester $1.5-4/kg
- Always request fabric swatches before bulk production
- Consider your target market's climate and lifestyle
Fabric selection is one of the most critical decisions in clothing manufacturing. The right fabric can make your garment comfortable, durable, and marketable. The wrong choice leads to returns, complaints, and damaged reputation.
This guide covers everything you need to know about choosing fabrics for your clothing line—from understanding GSM to comparing material options.
Understanding GSM (Grams per Square Meter)
GSM measures fabric weight—the higher the number, the heavier the fabric. This directly affects:
- Cost: Heavier fabrics use more material
- Warmth: Higher GSM = warmer garment
- Drape: Lower GSM flows better; higher GSM holds shape
- Durability: Generally, heavier fabrics last longer
| GSM Range | Best For | Examples |
|---|---|---|
| 120-150 | Light summer wear | Summer tees, linings |
| 160-180 | Standard tees | Basic t-shirts |
| 180-220 | Premium tees | Ring-spun cotton tees |
| 220-280 | Lightweight hoodies | Summer sweatshirts |
| 280-350 | Standard hoodies | French terry, sweats |
| 350-450 | Heavyweight | Winter hoodies, jackets |
Popular Fabric Types for Streetwear
1. Cotton
Pros: Soft, breathable, absorbent, hypoallergenic

2. Cotton-Polyester Blend
Pros: Reduced shrinkage, wrinkle-resistant, maintains color
Cons: Less breathable than 100% cotton
Best for: Uniforms, everyday wear, print-friendly
3. French Terry
Pros: Soft, looped-back for moisture wicking, breathable
Cons: Can pill if low quality
Best for: Hoodies, sweatshirts, joggers, light jackets
4. Fleece
Pros: Warm, soft, lightweight, quick-drying
Cons: Pilling over time, not wind-resistant
Best for: Cold-weather sweatshirts, lining
5. Polyester
Pros: Durable, moisture-wicking, wrinkle-resistant
Cons: Can feel synthetic, holds odors
Best for: Activewear, performance wear
Fabric for Different Garments
T-Shirts
- 100% Combed Cotton (180-220 GSM): Premium feel, soft
- Ring-Spun Cotton: Even softer, durable
- Cotton-Poly Blend (60/40): Reduced shrinkage
Hoodies & Sweatshirts
- French Terry (280-350 GSM): Year-round wear
- Fleece (280-360 GSM): Cold weather
- Heavyweight Cotton (350+ GSM): Premium segment
Joggers & Pants
- French Terry (280-320 GSM): Lightweight comfort
- Heavy Cotton (320-400 GSM): Structure
- Poly-Cotton Blend: Performance
Activewear
- Polyester-Spandex (10-20%): Stretch and recovery
- Nylon-Spandex: High-impact support
- Bamboo Fabric: Natural moisture-wicking
Choosing the Right Fabric for Your Brand
Consider Your Target Market
- Climate: Tropical = lighter GSM; Cold = heavier
- Lifestyle: Active = moisture-wicking; Office = crisp
- Price Point: Budget = poly-cotton; Premium = ring-spun

- Fabric Finish: Pre-shrunk, mercerized
- Certification: OEKO-TEX, GOTS for eco-friendly claims
Working with Manufacturers
- Request fabric swatches before production
- Get lab test reports for composition and shrinkage
- Specify GSM tolerance (+/- 5%)
- Confirm color matching (D65 light source)

Frequently Asked Questions
The best fabrics for streetwear are typically cotton and cotton blends. French terry (280-350 GSM) is popular for hoodies and sweatshirts, while ring-spun cotton (180-220 GSM) is ideal for t-shirts. These materials offer comfort, durability, and that classic streetwear look.
GSM (Grams per Square Meter) measures fabric weight. Lower GSM (120-180) is lightweight for summer tees; medium (180-280) works for year-round wear; higher GSM (280-400+) is heavy for hoodies and sweatshirts. GSM directly affects cost, warmth, and drape.
Cotton offers breathability, softness, and moisture absorption—great for everyday wear. Polyester provides durability, wrinkle resistance, and moisture-wicking. Blends (like 60% cotton/40% polyester) combine benefits: cotton's comfort with polyester's performance.
For activewear, look for moisture-wicking (polyester, nylon, bamboo), 4-way stretch (spandex blends 10-20%), and durability. Popular choices include polyester-spandex blends for yoga wear, nylon for high-impact sports, and merino wool for performance base layers.
French terry is a soft, looped-back fabric (typically 280-350 GSM) perfect for lightweight hoodies, sweatshirts, and joggers. It offers more breathability than fleece while maintaining warmth. The looped back provides moisture-wicking properties.
