The Ultimate T-shirt Fabric Guide: GSM, Cotton & Blanks

Everything you need to know about 180 GSM vs 240 GSM.

Fabric is where luxury meets utility. In the Indian climate, the choice of fabric can make or break a brand's repeat purchase rate.

What is GSM?

GSM stands for Grams per Square Meter. It measures the density and weight of the fabric. - **160-180 GSM:** Standard weight. Perfect for regular fit summer tees. - **200-220 GSM:** Mid-weight. Used for premium regular fits or light hoodies. - **240-280 GSM:** Heavyweight. The gold standard for Streetwear and Oversized silhouettes.

Combed vs Carded Cotton

Always choose **Combed Cotton**. Carded cotton is cheaper but contains impurities and short fibers that make the T-shirt feel "scratchy" and prone to pilling (burr formation). Combed cotton is smoother, stronger, and better for high-quality printing.

What is Bio-Wash?

Bio-wash is an enzyme treatment that removes peach-fuzz from the garment surface, making it extremely smooth and ensuring the print sticks perfectly without any texture interference.
