Is a 240 GSM T-Shirt Too Hot for Indian Weather? An Honest Answer

A 240 GSM t-shirt is warmer than a 180 GSM one, and in peak May heat in Delhi or Chennai you will notice it. But weight is only one of four factors deciding how hot a tee feels, cut, colour, weave and airflow matter just as much, and a well-cut 240 GSM relaxed tee is often more comfortable than a fitted 180 GSM one.
Why Weight Is Not the Whole Story
Heat discomfort comes mostly from fabric sitting against skin and trapping still, humid air. A fitted lightweight tee does exactly that, it clings across the back and chest with nowhere for air to move.
A relaxed cut in heavier fabric holds itself away from the body. Air moves through the gap. The fabric is heavier but far less of it touches you, and that trade often favours the heavier shirt.
It is the same principle behind loose cotton kurtas in Indian summer, the volume does the cooling, not the thinness. More on climate-appropriate cuts in what actually works in Delhi's 45°C summers.
When 240 GSM Genuinely Is Too Much
Peak summer afternoons, April to June across most of North and Central India
High humidity with no breeze, as in coastal Mumbai or Chennai in May
Extended physical activity or long commutes in direct sun
Anywhere you need fabric to dry fast after sweating
When It Is the Right Choice
October through March across most of India, comfortably the longer part of the year
Air-conditioned offices, where lightweight tees are often too cold
Evenings and indoor wear year-round
Hill stations and higher-altitude cities at almost any time
Anytime you want the tee to hold a structured silhouette
Why 100% Cotton Matters Here
Fibre content changes the heat equation more than most people expect. Cotton absorbs moisture and lets it evaporate; polyester repels it and holds a humid layer against the skin.
This is why a heavyweight 100% cotton tee frequently feels cooler in Indian humidity than a thin polyester blend, despite weighing considerably more. Weight is not the same thing as warmth.
The Practical Verdict
For roughly eight months of the year in most Indian cities, 240 GSM in a relaxed cut is comfortable and looks considerably better than a thin tee. For the four hottest weeks it is not the shirt for the afternoon sun.
That is an honest trade, worth knowing before buying rather than after. If you want one tee for every condition including peak heat, heavyweight is not it. If you want a tee that looks structured and lasts years, it is.
For reference, Shunya Theory tees are 100% cotton, 240 GSM (220 GSM on WARLI), screen printed, relaxed fit, XS(40) to XL(48), ₹1,349.
Frequently Asked Questions
Is 240 GSM cotton hot to wear in summer?
It is warmer than standard 180 GSM, and in peak Indian summer afternoons you will feel the difference. In a relaxed cut that holds fabric off the skin, it stays wearable most of the year outside the hottest weeks.
What GSM is best for Indian summers?
For peak summer specifically, 160 to 190 GSM in a loose cut is most comfortable. For year-round wear where you also want structure and durability, 220 to 240 GSM in a relaxed cut is the better all-rounder.
Does 100% cotton help with heat?
Yes. Cotton absorbs moisture and allows evaporation, which polyester does not. A heavyweight 100% cotton tee usually feels cooler than a lightweight polyester blend in humid conditions.
Does colour affect how hot a t-shirt feels?
Yes, in direct sunlight, dark colours absorb more heat outdoors. Indoors or in shade the difference is negligible, and cut matters far more than colour.
