What Makes a High-Quality Custom Sweatshirt? Fabric, GSM & Construction Explained
1. Fabric: The Foundation of a Quality Sweatshirt
Fabric choice determines comfort, durability, and perceived value.
Common Fabrics Used by Sweatshirt Manufacturers
• 100% Cotton Fleece – Soft, breathable, premium hand feel
• Cotton-Poly Blends (80/20 or 70/30) – Improved durability and shape retention
• French Terry – Lightweight, smooth exterior, ideal for modern casualwear
• Sustainable Fabrics – Organic cotton and recycled polyester blends
Professional sweatshirt manufacturers help brands select fabrics based on target market, climate, and retail positioning.
2. GSM Explained: Why Fabric Weight Matters
GSM (grams per square meter) measures fabric density and thickness.
Recommended GSM Ranges
| Use Case | GSM Range |
| Lightweight / Corporate | 260–300 GSM |
| Standard Retail | 300–340 GSM |
| Premium / Streetwear | 360–450 GSM |
Higher GSM sweatshirts feel heavier, warmer, and more premium, making them ideal for high-end custom collections.
3. Construction & Stitching Standards
High-quality custom sweatshirts require precise construction.
Key Construction Features
• Double-needle stitching on seams
• Reinforced shoulder seams
• Clean ribbed cuffs and hem
• Pre-shrunk fabric treatment
• Balanced fit and consistent sizing
Reliable custom sweatshirt manufacturers maintain strict sewing standards to ensure durability.
4. Printing & Embroidery Quality
Decoration methods affect both aesthetics and longevity.
Common Decoration Techniques
• Screen Printing – Cost-effective, durable for bulk orders
• Embroidery – Premium appearance, long-lasting
• DTG Printing – High detail, best for small runs
• Puff Print & Appliqué – Popular in streetwear
Top manufacturers advise on the best method based on design complexity and fabric type.
5. Fit, Pattern Making & Sizing Consistency
Even premium fabric fails if fit is poor.
Fit Considerations
• Accurate pattern grading
• Consistent measurements across sizes
• Market-specific fits (US, EU, Asia)
Experienced sweatshirt manufacturers provide sample fittings and revisions before bulk production.
6. Quality Control Process
Professional sweatshirt manufacturers follow multi-stage QC.
Typical QC Stages
• Fabric inspection
• In-line production checks
• Printing and embroidery review
• Final garment inspection
At Artisan Casual, every custom sweatshirt undergoes strict quality checks before shipment.
