Quick answer: 240 GSM means the fabric weighs 240 grams per square metre — heavyweight cotton that is more durable, more structured and softer when combed. Choose it for a tee you want to last; pick 180 GSM for lighter, breezier everyday wear.
GSM — grams per square metre — is the fabric’s weight, and it is the single best indicator of a t-shirt’s quality. Two shirts can both say “100% cotton” and feel completely different. GSM is why.
What GSM actually means
Take one square metre of fabric. Weigh it. That number is the GSM. The higher the number, the denser and heavier the weave:
- 150–180 GSM — light, soft, breathable; ideal for Indian summers and daily wear.
- 200–240 GSM — heavyweight, structured, durable; the “premium” tier.
- 250+ GSM — hoodie territory; too heavy for most tees.
Why 240 GSM feels better
- Drape — heavy cotton falls cleanly instead of clinging or tenting.
- Structure — it holds its shape through the day and through the wash.
- Longevity — denser fabric resists pilling and thinning.
- Softness — when the cotton is combed (long fibres, no short fuzzy ones), heavy feels smooth, not rough.
240 GSM or 180 GSM?
Choose 240 GSM if you want a tee that looks sharp, layers well under jackets, and lasts years — like the Samay Raina unisex classic crew in 100% combed cotton. Choose 180 GSM for light, airy everyday tees — like the I’m Not Mean tee — when you want maximum breathability. Our 180 vs 240 GSM guide goes deeper.
Caring for heavyweight cotton
Wash inside out in cold water, hang dry, and skip the iron on any printed area. Heavyweight cotton also means the print has a better base — the print care guide keeps both fabric and design looking new.
Frequently Asked Questions
Is 240 GSM good for t-shirts?
Yes — it is the premium standard: structured, durable and comfortable when combed.

Bottom line
GSM is the easiest shortcut to t-shirt quality. 240 GSM combed cotton gives you a structured, durable, smooth tee that feels noticeably better than a cheap 150 GSM blank — and lasts longer doing it. That is why it is the fabric choice for the classic crew.
