Single Jersey vs French Terry vs Three-Thread: Choosing the Right Knit
Single jersey, French terry and three-thread come from the same family but serve very different purposes. We clarify the differences in structure, weight, brushing and use.
Making t-shirts or sweatshirts? Summer or winter? The answer usually comes down to a choice between three fabrics: single jersey, French terry and three-thread fleece. All three come from the same knit family but differ sharply in structure and use. This guide breaks down the key differences so you can choose correctly.
What They Share
All three are weft knits and can be made from the same yarn qualities (combed/carded), in cotton, CVC and viscose blends, with optional elastane. The main difference is the number of yarns entering the knit — and the resulting thickness, weight and drape.
Single Jersey: Lightest and Most Common
Single jersey is a single-layer knit, the thinnest of the three at 120–220 gsm. Flat V-loops on the face, horizontal loops on the back, with a light, fluid drape. It is the go-to for t-shirts, dresses, underwear and sweatshirt linings.
French Terry (2-Thread): The Sweatshirt Base
French terry adds a second loop yarn that creates the terry back, making it thicker and warmer than single jersey at 220–320 gsm. Unbrushed stays light for spring hoodies; brushed adds warmth for classic winter sweatshirts.
Three-Thread: Thickest and Fullest
Three-thread fleece adds a third binding yarn for extra thickness and a full, draping hand at 300–350 gsm — ideal for oversize and streetwear. Its brushed version is the warmest option.
Comparison
| Feature | Single Jersey | French Terry | Three-Thread |

| Season | Spring-summer | All season | Autumn-winter |
| Main product | T-shirt | Sweatshirt / hoodie | Winter sweat / oversize |
What Is Brushing (Şardon)?
Brushing raises the fibres on the fabric back, softening the surface and trapping air for insulation. Brushed fabrics suit winter products; unbrushed suit transitional and summer items. Brushing is a key option for French terry and three-thread, but is generally not applied to single jersey.
Conclusion
Single jersey, French terry and three-thread form the thin-medium-thick axis of knits. The right choice depends on season, desired drape and brand positioning. For samples and pricing, contact us or browse all our knits on the fabric types page.
