Heavyweight 100% Cotton Jersey Fabric | 310gsm (9oz) | 4-Way Stretch

Create luxurious, cozy garments with our Heavyweight 100% Cotton Jersey Fabric. Weighing in at a substantial 310 GSM (9oz), this is far superior to standard thin t-shirt knits. It offers a thick, reassuring drape that feels premium to the touch and provides complete opacity (it is not see-through).

Despite its weight, this fabric features an incredible 4-Way Stretch (70% Vertical / 50% Horizontal), moving freely with your body while retaining its shape. It is the ultimate choice for high-quality loungewear that needs to be both warm and breathable.

Why Choose This Heavyweight Knit?

• Premium Weight (310gsm): Double the weight of standard jersey. It feels like a high-end sweatshirt or boutique legging fabric.

• 100% Cotton Breathability: Unlike many heavy knits which are polyester blends, this is 100% natural cotton, keeping you cool even though the fabric is thick.

• High Performance Stretch: With 70% vertical stretch, it is perfect for fitted garments like leggings or bodysuits that need to stretch lengthways without feeling restrictive.

• Opaque: Completely non-see-through, making it “squat proof” for bottoms.

Ideal Uses

• Loungewear: Joggers, hoodies, and sweatshirts.

• Bottoms: Thick leggings, cycling shorts, and skirts.

• Baby: Warm baby blankets, sleep sacks, and winter rompers.

• Upholstery: Its thickness allows it to be used for stretch covers on sofas or cushions.

Expert Sewing Tips for Heavy Knits

1. Needle Choice: Use a Jersey / Ballpoint Needle (Size 90/14). The thicker fabric requires a slightly larger needle to penetrate the layers without skipping stitches.

2. Stitch Settings: Use a Lightning Bolt Stitch or a narrow Zig-Zag. Because this fabric has 70% stretch, a straight stitch will snap when you put the garment on.

3. Seams: If you don’t have an overlocker (serger), don’t worry! This fabric is stable enough to sew on a regular machine, and because it’s a knit, the edges won’t fray.
