Defining GSM Categories

Fabric weights generally fall into three main categories:

1. Lightweight (130 - 160 GSM) * **Best For:** Sports jerseys, promotional giveaways, activewear, and high-heat summer fests. * **Characteristics:** Extremely breathable, light, and quick-drying. However, it can drape loosely and may show slight transparency on light colors.

2. Mediumweight (170 - 200 GSM) * **Best For:** Standard corporate uniforms, college merchandise, retail apparel, and casual streetwear. * **Characteristics:** The perfect sweet spot. Our signature 180 GSM combed cotton T-shirt provides a structured fit, excellent print stability, and is comfortable for year-round wear in India.

3. Heavyweight (220 - 360 GSM) * **Best For:** Premium oversized streetwear T-shirts (240 GSM), crewneck sweatshirts (300 GSM), and winter hoodies (320 GSM). * **Characteristics:** Thick, cozy, and highly structured. Heavyweight garments drape elegantly off the shoulders and hold embroidery designs without puckering.

The Impact of GSM on Printing Quality

• **Embroidery:** Heavyweight fabrics (240+ GSM) hold high stitch counts perfectly. Lightweight fabrics can pucker under dense thread designs.
• **Puff Printing:** The volumetric expansion of 3D puff print looks outstanding on thick, structured 240 GSM oversized streetwear, whereas it can cause lightweight fabric to warp.
• **DTF and Screen Prints:** Medium to heavyweight cotton provides a smooth, stable bed for clean plastisol curing and digital film transfers.
