The same fabric family at three weights. You can see the knit density change; you can't see the GSM number.
What GSM means
GSM stands for grams per square metre — the weight of one square metre of the fabric.
- Lower GSM = lighter, thinner fabric
- Higher GSM = heavier, denser fabric
That's the whole definition. Note what's missing from it: nothing about softness, nothing about durability, nothing about yarn quality, nothing about how long the collar holds its shape. GSM measures weight, not quality.
Two 200 GSM polos from different factories can feel completely different, because GSM says nothing about fibre length, yarn spinning method, knit density or finishing. This is precisely why you should always feel a swatch rather than compare quote sheets.
The three weights that matter for polos
For corporate and uniform polos in India, virtually everything worth buying sits between 180 and 240 GSM.
180 GSM — light and fast-drying
Best for performance and outdoor use. At this weight, polyester dry-fit fabrics move sweat efficiently and dry quickly, which matters more than substance when someone is working outdoors at 35°C.
Suits: delivery and field teams, security in hot sites, sports and running events, promotional giveaways, humid coastal conditions.
Trade-off: feels less substantial in hand, and on light colours a thin fabric can show through. Not the right choice if the shirt needs to read as premium. Our Honeycomb Dry Fit polo (100% polyester, 16 colours) sits here.
200 GSM — the practical middle
Enough weight to feel proper without becoming warm. Holds an embroidered logo cleanly, resists wrinkling better than lighter knits, and survives frequent washing.
Suits: most office and retail uniforms, service teams, staff who wear the shirt daily and wash it constantly. Our Mars Wrinkle-Free polo (100% polyester piqué, 9 colours) sits here.
240 GSM — substantial and premium
The weight most people mean when they say a shirt "feels good." Better structure, better opacity, better drape.
Suits: customer-facing staff, senior team members, hospitality front-of-house, anything where the uniform is part of the brand impression.
Trade-off: warmer in peak Indian summer. Three of our five polos sit here: Spun Piqué (100% spun polyester, 22 colours), Polycotton Piqué (60/40) and Air Tex (100% cotton piqué).
So which GSM for corporate uniforms?
200 to 240 GSM is the working standard for corporate polos in India. That's where we set our own range and it's what we recommend to nearly every corporate buyer.
| If the priority is… | Choose |
|---|---|
| Outdoor work, heat, sweat, movement | 180 GSM dry-fit polyester |
| Daily office and retail wear, frequent washing | 200 GSM |
| Brand impression, customer-facing, premium feel | 240 GSM |
| Softness with polyester durability | 240 GSM spun polyester |
| Natural fibre feel, premium positioning | 240 GSM cotton piqué |

Why higher GSM isn't automatically better
This is the single most common misconception we deal with, and it costs buyers money. A poorly-made 240 GSM polo is not better than a well-made 200 GSM one. Durability depends far more on:
What actually drives polo durability
- ✓ Yarn quality — combed and ring-spun yarns resist pilling far better than carded open-end yarn at any weight
- ✓ Knit consistency — uneven knitting creates weak points regardless of weight
- ✓ Finishing — compacting controls shrinkage; bio-washing reduces surface fuzz and pilling
- ✓ Collar rib construction — the part that fails first, and it has almost nothing to do with body-fabric GSM
- ✓ Stitching and seam quality — a shirt fails at its seams, not in the middle of a panel
We've seen 190 GSM polos outlast 230 GSM ones, comfortably, because they were made with better yarn and finished properly.
GSM and comfort in Indian conditions
Weight and warmth correlate, but knit structure matters just as much. Piqué's textured knit circulates air noticeably better than a smooth jersey at the same weight — which is why a 240 GSM piqué polo can feel cooler than a 220 GSM jersey one.
For teams working outdoors through a Tamil Nadu or Rajasthan summer, prioritise fibre and knit over chasing a lower number: a 180 GSM moisture-wicking polyester piqué beats a 180 GSM cotton jersey every time on a hot day, because it moves sweat instead of holding it. The difference between knit types is covered in woven vs knitted fabrics.
What to ask instead of "what's your highest GSM?"
- What GSM is this, and what's the knit structure — piqué, jersey or interlock?
- Is the yarn combed or carded? Ring-spun?
- Has the fabric been compacted? What shrinkage should I expect?
- Has it been bio-washed?
- Can I have swatches of two weights to compare?
- What's the colour fastness like after industrial washing?
These tell you far more about how the shirt will look after six months than the GSM number alone.
Common mistakes
- Choosing the highest GSM available. Comfort in Indian heat matters more than heft, and you'll pay for weight your team doesn't want.
- Comparing quotes on GSM alone. Two quotes at 240 GSM can be entirely different products.
- Ignoring the knit structure. Piqué, jersey and interlock behave differently at identical weights.
- Assuming heavier lasts longer. Construction quality drives durability more than weight does.
Frequently asked questions
Is 240 GSM always better than 180 GSM?
No. GSM measures weight, not quality. A well-made 180 GSM dry-fit polo is a better choice for outdoor teams than a 240 GSM cotton one, and a badly-made 240 GSM shirt will lose to a well-made lighter one.
Which GSM is best for corporate polo shirts?
200 to 240 GSM covers most corporate uniform requirements in India. Go to 180 GSM only for performance and outdoor use.
Does higher GSM make a polo hotter?
Generally yes, but knit structure and fibre matter as much. A 240 GSM piqué can feel cooler than a 200 GSM jersey, and moisture-wicking polyester feels cooler than cotton in humid heat regardless of weight.
Should I compare manufacturers on GSM?
Only as one line item. Compare fibre content, yarn type, knit structure, finishing and, above all, a physical swatch.
What GSM are Anuvavi's corporate polos?
180 GSM Honeycomb dry-fit, 200 GSM Mars wrinkle-free, and 240 GSM in Spun Piqué, Polycotton Piqué and Air Tex cotton.
Author's note
If you're stuck between two weights, ask us for swatches of both. It's the cheapest decision-making tool in the whole process and it settles the argument in about ten seconds.
Happy manufacturing.
