GSM stands for grams per square metre. It's the weight of one square metre of fabric, and it's the simplest way to compare how substantial a garment will feel before you ever touch it.
A higher number means more cotton in the same area. That usually translates to a denser, more opaque fabric that holds its shape — but it also means more warmth. Neither is better on its own; it depends on how and where you'll wear it.
The NAN range, from lightest to heaviest
| Fit | GSM | Best for |
|---|---|---|
| Regular T-Shirt | 180 | Everyday wear, hot days, layering under shirts |
| Polo T-Shirt | 220 | A sharper look that still breathes |
| Oversized T-Shirt | 240 | Boxy streetwear silhouette that drapes, not clings |
| French Terry Tee | 240 | Structured feel with a soft looped back |
| Sweatshirt | 350 | Cool evenings, travel, winter layering |
| Oversized Hoodie | 350 | Maximum warmth and that heavyweight hand-feel |
How weight changes the way a tee looks
- Drape: heavier fabric falls straighter and hides creases, which is why oversized cuts are usually 240 GSM and up.
- Opacity: lighter tees can show what's underneath in bright light; heavier ones don't.
- Structure: collars and hems on heavier fabric stay flat for longer.
- Breathability: lighter fabric moves air faster — a real advantage in Indian summers.
A simple rule of thumb
If you'll be outdoors in the heat, start at 180 GSM. If you want the oversized streetwear look all year, 240 GSM is the sweet spot. Save 350 GSM for evenings, air-conditioned offices, travel and winter.
Weight isn't about quality alone — it's about choosing the right fabric for the life you actually live.
