"I just want it to feel premium."
This is one of the most common things new clothing brand founders tell their manufacturers — and one of the least useful instructions a factory can receive. "Premium" means different things to different people, and without specific fabric specifications, you'll get whatever the factory decides to use.
This guide gives you the vocabulary and knowledge to tell your manufacturer exactly what you want.
What Is GSM and Why Does It Matter?
GSM (grams per square meter) measures the weight of a fabric. It's the single most important spec for a t-shirt because it directly affects:
- How the shirt feels (lightweight and breathable vs. substantial and structured)
- How it drapes on the body
- How durable it is over time
- How well it holds prints and dyes
- The perceived value to the customer
| GSM Range | Feel & Use | Best For | Examples |
|---|---|---|---|
| 130–160 GSM | Very light, sheer | Summer basics, activewear underlayers | Fast fashion tees |
| 160–180 GSM | Light, standard | Everyday basics, high-volume brands | Gildan 64000, standard blanks |
| 180–220 GSM | Mid-weight, comfortable | Most clothing brands, versatile use | Premium basics, retail tees |
| 220–260 GSM | Substantial, structured | Streetwear, graphic tees, quality brands | "Boxy" fits, oversized drops |
| 260–320 GSM | Heavy, premium | High-end streetwear, cold-weather tees | Heavyweight "luxury" basics |
Our recommendation for most streetwear and clothing brands: 220–260 GSM. This range delivers the substantial feel customers associate with premium products while remaining comfortable to wear.
Cotton Composition: What the Percentages Mean
100% Cotton
The most natural option. Breathable, soft, and great for printing. Can shrink more in the wash and may wrinkle. Standard for most t-shirt brands.
Cotton/Polyester Blends
| Blend | Feel | Pros | Cons |
|---|---|---|---|
| 100% Cotton | Soft, natural | Breathable, excellent print surface, eco-preferred | More shrinkage, wrinkles easier |
| 80% Cotton / 20% Poly | Slightly smoother | More shape retention, less shrinkage | Slightly less breathable |
| 65% Cotton / 35% Poly | Crisp, holds shape | Very durable, low shrinkage, color-fast | Less premium feel, not eco-friendly |
| 50% Cotton / 50% Poly | Smooth, athletic | Moisture-wicking, ideal for activewear | Not preferred for fashion tees |
| 100% Polyester | Synthetic, smooth | Best for sublimation printing | Not natural, less comfortable for everyday wear |
Combed vs. Ring-Spun vs. Open-End Cotton
- Open-end cotton: Most common, most affordable. Standard quality.
- Ring-spun cotton: Softer and stronger than open-end. Better drape. Preferred for mid-premium brands.
- Combed cotton: The softest option. Short fibers removed, leaving long, uniform strands. Best for premium brands.
For a premium brand: Specify "combed ring-spun cotton" with your GSM. This is the spec used by most quality streetwear brands.
Fabric Types Beyond Basic Jersey
Jersey (Standard T-Shirt)
The standard t-shirt fabric. Single-knit structure, smooth front, looped back. Versatile and the most common for streetwear and casual brands.
French Terry
Looped texture on the inside, smooth on the outside. Used for sweatshirts and heavier tees. Great for drop-shoulder and oversized styles.
Waffle Knit
Textured grid pattern. Adds visual interest and a distinctly premium feel. Popular for limited-edition pieces and layering tees.
Pique
Raised textured weave. Most common in polo shirts but increasingly used in oversized t-shirt silhouettes for a premium look.
How to Specify Fabric to Your Manufacturer
Instead of saying "soft cotton," use this format:
"240GSM, 100% combed ring-spun cotton, single jersey, pre-shrunk"
This single line of text tells your factory everything they need to source the right material and give you an accurate quote.
Fabric and Print Compatibility
| Print Method | Best Fabric | Why |
|---|---|---|
| Screen Printing | 100% Cotton, 180–260 GSM | Ink bonds best to natural fibers |
| DTG (Direct-to-Garment) | 100% Cotton, pre-treated | Requires natural fiber surface for ink absorption |
| Heat Transfer | Cotton or Cotton/Poly blend | Works on most fabrics |
| Embroidery | Any, 200 GSM+ | Heavier fabric supports embroidery without puckering |
| Sublimation | 100% Polyester | Only bonds permanently to synthetic fibers |
