June 9, 2026 – 8 PM IST – The Fabric Lab #1: GSM Explained
Why Fabric Weight Changes Everything – The Definitive GSM Guide for Indian Streetwear
The Number on the Label That Most Brands Don’t Want You to Understand
180 GSM. 220 GSM. 260 GSM. 300 GSM.
You’ve seen these numbers on Euphor product pages. You’ve probably wondered what they mean. And you’ve definitely noticed that most fast fashion brands don’t mention GSM at all.
That’s not an accident.
GSM is the single most important number in fabric quality. And most brands hide it because their numbers are embarrassing.
This is the Fabric Lab – Euphor’s deep dive into the science behind premium cotton. No marketing language. No vague claims. Just the honest truth about what makes fabric good, and why it matters for how you dress in India.
Start here: GSM.
🔥 Tonight’s Drop – 9 PM IST: Fabric Lab Launch Bundle – our 180 GSM, 220 GSM, and 260 GSM tees together for the first time. Feel the difference. 25 bundles only. Save this page.
What Is GSM?
GSM stands for Grams per Square Metre.
It’s the measurement of how much a fabric weighs per square metre of material. A higher GSM means more cotton fibres per square metre – which means a denser, heavier, more substantial fabric.
Think of it like paper. A 60 GSM newspaper tears easily, goes transparent when wet, and doesn’t hold its shape. A 300 GSM business card is rigid, opaque, and feels premium in your hand. Same material category. Completely different experience.
Cotton fabric works the same way.
A 120 GSM fast fashion tee: Thin, see-through in sunlight, loses shape after 10 washes, goes transparent when you sweat.
A 220 GSM premium tee: Substantial, opaque, holds its shape through 100+ washes, looks as sharp at 9 PM as it did at 9 AM.
Same category. Completely different experience. GSM is why.
The GSM Spectrum – What Each Weight Means
100–150 GSM – Ultra-Light / Fast Fashion Territory
This is the weight of most fast fashion tees – the ₹299 Myntra special, the free event tee, the promotional giveaway.
What it feels like: Thin, almost papery. You can see your hand through it when held up to light.
What it does: Goes see-through when wet or in direct sunlight. Loses shape after 5–10 washes. Develops holes at stress points (collar, underarms) within months.
Where it works: Nowhere, really. It’s cheap to produce and cheap to buy. That’s its only advantage.
Euphor verdict: We don’t make anything below 180 GSM. This weight is not premium cotton – it’s cotton-adjacent.
150–180 GSM – Light / Summer Weight
The lightest weight that can genuinely be called premium. Used for ultra-breathable summer pieces in extreme heat climates.
What it feels like: Light but substantial. Noticeably better than fast fashion. Still has some drape.
What it does: Breathes exceptionally well. Ideal for 38–42°C conditions. Holds shape reasonably well through washes.
Where it works: Chennai and Mumbai peak summer (May–June). Outdoor events in extreme heat. Layering base under heavier pieces.
Euphor use: Our 180 GSM pieces are designed specifically for South India’s peak summer and coastal humidity.
180–220 GSM – The Indian Sweet Spot
This is the most versatile GSM range for Indian conditions – and the weight that defines the Euphor Classic Tee.
What it feels like: Substantial, smooth, premium. The weight you notice when you pick it up. Opaque in all conditions.
What it does: Breathes well enough for 33–35°C days. Substantial enough for 20–22°C evenings. Holds its shape through 100+ washes. Stays opaque in sweat and sunlight.
Where it works: Every Indian city, every season except peak summer in coastal cities. The year-round Bangalore tee. The Delhi summer evening tee. The Pune all-season staple.
Euphor use: Our 220 GSM Classic Tee is our most versatile piece – designed to work across all 6 major Indian cities year-round.
220–260 GSM – Mid-Weight / The Hoodie Zone
The weight range of premium hoodies, sweatshirts, and heavier tees. This is where fabric starts to feel genuinely luxurious.
What it feels like: Substantial, warm, structured. The weight that makes a hoodie feel like a hoodie – not a thin sweatshirt.
What it does: Provides real warmth. Holds structure through years of wear. Drapes beautifully. Looks premium under any lighting condition.
Where it works: Bangalore year-round evenings. Delhi and Hyderabad monsoon and winter. Pune monsoon. Hill station trips. AC environments everywhere.
Euphor use: Our 260 GSM Classic Hoodie – the piece that works from Bangalore’s cool evenings to Delhi’s winter mornings.
260–300 GSM – Heavyweight / Statement Pieces
The weight of premium outerwear, varsity jackets, and statement pieces. This is where fabric becomes a structural element of the garment.
What it feels like: Substantial, structured, premium. The weight that makes a varsity jacket feel like a varsity jacket.
What it does: Provides significant warmth. Holds its shape permanently. Develops a beautiful patina with wear. Lasts decades, not seasons.
Where it works: Delhi and Hyderabad winters. Hill stations. Bangalore and Pune cool evenings. Statement outerwear year-round.
Euphor use: Our 280 GSM Varsity Jacket – the piece designed to last 10+ years.

Why Fast Fashion Brands Don’t Mention GSM
Here’s the uncomfortable truth: most fast fashion tees sold in India are 120–150 GSM.
At that weight, the fabric is technically cotton – but it performs nothing like premium cotton. It’s thin enough to be see-through. It loses shape within weeks. It develops holes within months.
Fast fashion brands don’t mention GSM because if you knew the number, you wouldn’t buy the product.
At Euphor, we put GSM on every product page. Not as a marketing claim – as a specification. The same way a car manufacturer lists engine displacement or a phone manufacturer lists battery capacity.
GSM is the spec that tells you what you’re actually buying. Demand it from every brand you shop.
The GSM Test – How to Check Any Tee You Own
You can estimate the GSM of any tee you own with this simple test:
The Light Test: Hold the tee up to a bright light source. If you can see your hand clearly through the fabric, it’s below 180 GSM. If the fabric is opaque, it’s 180 GSM+.
The Pinch Test: Pinch a small section of fabric between your fingers. If it feels thin and papery, it’s below 180 GSM. If it has substance and body, it’s 180 GSM+.
The Drape Test: Hold the tee by the shoulders and let it hang. If it falls flat and limp, it’s below 180 GSM. If it has structure and drape, it’s 180 GSM+.
Try this with every tee in your wardrobe. The results will change how you shop.

Frequently Asked Questions – GSM Fabric
Q: What does GSM mean in fabric?
A: GSM stands for Grams per Square Metre – the measurement of how much a fabric weighs per square metre of material. A higher GSM means more fibres per square metre, resulting in a denser, heavier, more substantial fabric. It’s the single most important quality indicator for cotton fabric.
Q: What is a good GSM for a t-shirt?
A: For Indian conditions, 180–220 GSM is the premium sweet spot. 180 GSM for peak summer in coastal cities. 220 GSM as the year-round standard for most Indian cities. Below 160 GSM is fast fashion territory – the fabric will be thin, see-through, and short-lived.
Q: What GSM is best for Indian summer?
A: 180–200 GSM for peak summer (38–42°C) in coastal cities like Mumbai and Chennai. 200–220 GSM for inland cities like Delhi and Hyderabad where the heat is intense but less humid. 220 GSM works year-round in Bangalore and Pune where temperatures are more moderate.
Q: Is higher GSM always better?
A: Not always – it depends on the climate and occasion. Higher GSM means more warmth and substance, which is ideal for cooler climates and evenings. But in peak summer heat (40°C+), a 180–200 GSM tee is more comfortable than a 260 GSM piece. The right GSM depends on your city, season, and occasion.
Q: What GSM do fast fashion brands use?
A: Most fast fashion tees sold in India are 120–150 GSM – which is why they’re thin, see-through, and short-lived. Fast fashion brands rarely mention GSM because the number would reveal the product’s poor quality. Always ask for GSM before buying any tee.
Q: What is 220 GSM fabric like?
A: 220 GSM premium cotton is substantial, opaque, and smooth. It holds its shape through 100+ washes, stays opaque in sweat and sunlight, breathes well enough for 33–35°C days, and looks as sharp at 9 PM as it did at 9 AM. It’s the Euphor Classic Tee weight – designed to be the year-round standard for all 6 major Indian cities.
Q: How do I check the GSM of a t-shirt?
A: Three tests: (1) Light test – hold up to light; if you can see your hand through it, it’s below 180 GSM. (2) Pinch test – if it feels thin and papery, it’s below 180 GSM. (3) Drape test – if it falls flat and limp, it’s below 180 GSM. Premium fabric (180 GSM+) is opaque, has body, and drapes with structure.
Q: What GSM is best for hoodies?
A: 260–300 GSM for premium hoodies. 260 GSM is the Euphor sweet spot – substantial enough for real warmth, light enough for Bangalore’s year-round evenings and Delhi’s monsoon. 280–300 GSM for Delhi and Hyderabad winters and hill station trips.
Q: Why does GSM matter for streetwear?
A: GSM determines how a garment looks, feels, performs, and lasts. Higher GSM fabric holds its shape longer, looks more premium under any lighting, stays opaque in all conditions, and survives more washes. For streetwear – where the tee is the hero piece – GSM is the difference between a garment that looks good for 6 months and one that looks good for 6 years.
