5 Heavyweight Streetwear Fabric Types
French Terry
280–480gsmConstruction
Single-faced knit with loops on the reverse (interior) side and a smooth flat face
Hand-Feel
Smooth exterior, looped interior - lighter-feeling than loop-back fleece for the same weight. Breathable due to loop structure.
Best For
Quality hoodies, sweatshirts, sweatpants, and any garment where a smooth exterior is desired
Spec Tip
Specify GSM range, cotton content (100% or cotton-poly blend), and whether you want a brushed or unbrushed interior loop.
The most common base fabric for premium streetwear hoodies. Fenalt sources French Terry fleece in the 350–480gsm range.
Loop-Back Fleece (Heavy Fleece)
300–500gsmConstruction
Three-thread construction - face yarn, loop yarn, and binding yarn. Loops are on the interior (reverse) side. May be brushed for a softer feel.
Hand-Feel
Very warm and structured. Heavier than French Terry at equivalent GSM due to denser loop construction.
Best For
Heavyweight hoodies and sweatshirts where maximum warmth and structure are priorities
Spec Tip
Request a brushed vs unbrushed specification - brushing the interior loops softens the hand-feel significantly.
Often used interchangeably with French Terry in casual conversation, but technically a different construction. Loop-back fleece at 400gsm+ produces the signature 'chunky' hand-feel of premium heavyweight streetwear.
Combed Cotton Single Jersey
180–300gsmConstruction
Single-faced plain knit. Combing removes short fibres before spinning, producing smoother, stronger yarn.
Hand-Feel
Smooth, soft, and drapey at lower weights. Structured and heavy at 260gsm+. Excellent for direct-to-skin wear.
Best For
Premium heavyweight t-shirts (220–300gsm), long-sleeve tees, and any garment requiring a smooth, premium surface
Spec Tip
Always specify combed (not carded) cotton for premium positioning. Also specify yarn count - finer yarns produce a smoother fabric surface.
Combed cotton at 250–300gsm is the standard for heavyweight premium tees. Fenalt sources combed cotton single jersey in the 180–300gsm range.
Piqué (Waffle / Textured Knit)
200–350gsmConstruction
Textured knit with a geometric raised pattern on the face. More structural than single jersey.
Hand-Feel
Breathable, structured, with a distinctive textured surface. Less stretchy than jersey.
Best For
Polo shirts, structured t-shirts, boxy-fit layering pieces, and garments where texture is a design element
Spec Tip
Specify piqué type (waffle, honeycomb, birdeye) as each produces a different texture density.
Less common in core streetwear but popular in fashion-forward and luxury streetwear collections.
Polar Fleece
200–450gsmConstruction
Synthetic (polyester) knit with a brushed surface on both sides. Very different from cotton French Terry.
Hand-Feel
Very warm, very soft. Lightweight for warmth due to polyester thermal efficiency.
Best For
Outerwear fleece layers, athletic warm-up pieces, and cold-weather streetwear
Spec Tip
Recycled polyester (rPET) options exist and are increasingly specified by sustainability-conscious brands.
Polyester fleece is not typical for core streetwear aesthetics but is used in technical or outdoor-adjacent collections.
Questions
Frequently Asked Questions
What is the difference between French Terry and regular fleece?
French Terry has a smooth flat face and unbrushed looped interior. Regular fleece (or loop-back fleece) is typically wire-brushed on the interior for a softer, fuzzy feel. Both can be produced in similar GSM ranges but have different hand-feel characteristics. French Terry feels crisp and structured; brushed fleece feels warmer and softer.
What fabric do most premium streetwear hoodies use?
Most premium streetwear brands use French Terry or heavy loop-back fleece, typically in the 400–480 GSM range. Some ultra-heavyweight luxury brands go above 500 GSM. 100% combed cotton is preferred for pure retail positioning, though 80/20 CVC blends add shape retention.
What fabric does Fenalt source for streetwear brands?
Fenalt sources combed cotton single jersey in the 180–300 GSM range and heavy French Terry fleece in the 350–480 GSM range directly from audited mills in Dhaka, Bangladesh.
Why is 280 GSM single jersey preferred for streetwear t-shirts?
A 280 GSM single jersey is thick enough to maintain a boxy, structured silhouette without clinging to the body, offering zero show-through transparency and a clean canvas for screen printing.
How does fabric weight affect hoodie ribbing choices?
Heavy 450 GSM fleece hoodies require heavy 400 GSM 2x2 cotton/spandex ribbing at cuffs and waistbands. Using lightweight ribbing on a heavy body causes sagging and collar deformation after washing.
Does 100% cotton French Terry shrink more than poly-cotton blends?
Yes. 100% natural cotton French Terry experiences 3% to 5% natural wash shrinkage unless mechanically compacted or bio-washed by the factory prior to garment cutting.
