Three product pages, three different GSM numbers, no explanation of which one is right for July in Hyderabad. This is the standard Indian polo shopping experience, and it is solvable in about a thousand words.
The shorter version is this. GSM tells you fabric weight per square metre. For piqué polos sold in India, the useful range is 180 to 280. Inside that band, lighter is breathier and shorter lived, heavier is more polished and warmer. The sweet spot for most Indian use is 200 to 230, with caveats for what weave and yarn it is wrapped around. Everything below is the working.
What GSM measures
GSM stands for grams per square metre. It is a standard textile weight measurement and is codified in ISO 3801. The basic explanation does not get more complicated. GSM is a unit used to measure the weight of textiles, so a 200 GSM polo means one square metre of that fabric weighs 200 grams.
It does not tell you fibre, weave, staple length, spinning quality, or knit structure. It tells you how much fabric you are getting per unit area. That is useful, but only inside a category where the other variables are roughly comparable. For piqué polos, that category is well defined enough for the number to mean something.
The polo GSM band, 180 to 280
For a piqué polo, fabric weighing between 180 and 280 GSM strikes a balance between comfort, breathability and durability. Below 180, the polo is closer to a t shirt knit, and the collar will not stand. Above 280, you are in winter rugby shirt territory, which is great for a Bangalore November evening on a Koramangala terrace and uncomfortable for a Delhi May afternoon.
Inside the band, the same source breaks it down further. Lightweight piqué at 180 to 200 GSM offers breathability and softness. Medium weight piqué at 201 to 220 GSM suits everyday wear. Heavier piqué at 221 to 280 GSM provides durability, warmth, and a polished look.
What each band feels like, lasts like, looks like
The reason GSM matters in a buying decision is that it changes the polo's role in the wardrobe. A 180 GSM polo is a hot weather companion. A 250 GSM polo is an all year office piece. They are not interchangeable, even though both pages will call themselves "premium pique."
| GSM band | Feels like | Best for | Watch out for |
|---|---|---|---|
| 160 to 180 | Soft t shirt | Peak summer indoors | Collar will not stand, short life |
| 180 to 200 | Light piqué | Hot weather, breathable | Less polished, thinner hand |
| 200 to 230 | Mid piqué | Indian office, all year | Need spandex for recovery |
| 230 to 260 | Substantial | Cooler months, formal lean | Warm in May, June |
| 260+ | Heavy rugby | Winter, evening | Too warm most of the Indian year |
This matters more in a city like Bengaluru where the same week can run 16 at night and 28 at noon. We mapped a week's worth of polo, trouser and shacket choices for exactly that range in the Bengaluru work week dressed.
The market reference points sit inside this band. The Lacoste L.12.12 is widely reported as around 185 GSM in the classic version and lighter in the LIGHT variant, putting it in the lower end of the band. Ralph Lauren's piqué is reported at around 220 to 250 GSM, sitting squarely in the mid to heavy range. Most polos in the market fall between 150 and 250 GSM, which confirms the band but does not tell you where to land inside it.
Why GSM alone is not the answer
This is the part most polo coverage skips. A 220 GSM polo built on short staple cotton with no spandex and a loose knit will pill, sag at the collar, and lose shape in fifteen washes. A 200 GSM polo built on long staple cotton with 4% spandex and a tight piqué knit will outlast it by years. The number is necessary, not sufficient.
The heavier GSM used in quality piqué makes it long lasting and naturally wrinkle resistant, and thanks to its structured weave, piqué does not sag or lose its silhouette as quickly as regular cotton. The phrase "quality piqué" is doing a lot of work in that sentence. It means long staple cotton, ring spun yarn, tight knit, and ideally a small spandex content for recovery.
The same logic decides whether a shirt collar lasts a Diwali. Construction beats nominal spec across the wardrobe, and the shirts collection is built on the same principle.
There is one more asymmetry worth knowing. Some references suggest 90 to 170 GSM is best for summer clothing, but those numbers describe woven shirting like poplin and voile, not knit piqué. Piqué's honeycomb texture breathes better than woven cotton at the same GSM because the structure itself creates air pockets. A 200 GSM piqué is not a 200 GSM poplin. Do not import the woven number into the knit conversation.
The number to look for if you are buying for Indian conditions
Two hundred to two thirty GSM, on long staple cotton, with three to five percent spandex, in a proper piqué knit. That is the Indian working sweet spot. It is breathable enough for a 33°C Bangalore April, warm enough for a 14°C December morning, structured enough for the collar to stand through a client meeting, and elastic enough to recover after a Delhi metro rush hour.
PULSE VII, the Sigma Code polo, sits in the upper mid band on long staple cotton with 4% spandex, ribbed collar and cuffs, and a side vent hem. Six colourways, BLACK, WHITE, RED, BROWN, KHAKI and GREY. The full range is on the polos collection page. We wrote separately about a single polo doing a full Delhi day across commute, AC meeting and evening drinks if you want to see the same spec at work in real conditions.
The number to remember when you next read a product page is not the brand. It is two hundred to two thirty, knit not woven, long staple, with spandex. If the page does not list these, the page is hiding the answer.
