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 the Euphor Classic T-Shirt product page. 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.
🔥 Tonight’s Drop – 9 PM IST: Fabric Lab Launch Bundle – our Classic T-Shirt and Terry Oversized Tee 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.
The Euphor Classic T-Shirt at 220 GSM: 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.
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.
Where it works: Chennai and Mumbai peak summer (May–June). Outdoor events in extreme heat. Layering base under the Terry Oversized Tee.
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 T-Shirt and Ringer T-Shirt.
What it feels like: Substantial, smooth, premium. The weight you notice when you pick up the Classic T-Shirt. Opaque in all conditions.
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: The Classic T-Shirt and Ringer T-Shirt at 220 GSM – our most versatile pieces, designed to work across all 6 major Indian cities year-round.
220–260 GSM – Mid-Weight / The Heavyweight Zone
The weight range of premium heavyweight tees. This is where fabric starts to feel genuinely luxurious.
What it feels like: Substantial, warm, structured. The weight that makes the Terry Oversized Tee feel like a statement piece.
Where it works: Bangalore year-round evenings. Delhi and Hyderabad monsoon and winter. Pune monsoon. AC environments everywhere.
Euphor use: The Terry Oversized Tee at 260 GSM – 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 and statement pieces. This is where fabric becomes a structural element of the garment.

Why Fast Fashion Brands Don’t Mention GSM
Most fast fashion tees sold in India are 120–150 GSM. 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 – the Classic T-Shirt, the Ringer T-Shirt, the Terry Tee, and the Raglan. Not as a marketing claim – as a specification.
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
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. The Euphor Classic T-Shirt at 220 GSM is fully opaque.
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 – like the Classic T-Shirt – 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 like the Raglan, it’s 180 GSM+.
Try this with every tee in your wardrobe. The results will change how you shop.
