Micro-knit polyester: the short answer
Micro-knit polyester works in Indian heat for short, active or breezy days, and it is not the best choice for long, still, humid ones. It dries quickly and holds a printed design sharply, but it does not take up sweat the way cotton does. Choose it for a walk, a game or an evening out, and choose cotton for a full day at a desk.
We make both fabrics, so we have no reason to push one over the other. This is a plain look at what micro-knit polyester is good at, what it is not, and which EKVAAR pieces use it.
What is in the Kaal Grid and Rui pieces
Three Street pieces use polyester, and each is described on its product page with its weight.
- The Kaal Grid Oversized Tee at ₹699 is an oversized tee in 240 GSM micro-knit polyester, with a folded neck and an all-over EKVAAR glyph grid.
- The Kaal Grid Shorts at ₹699 are relaxed shorts in the same 240 GSM micro-knit polyester, with a drawstring waist and the same grid.
- The Rui Floral Crop Top at ₹599 is a cropped top in 180 GSM spun polyester, printed all over with florals and EKVAAR lettering.

GSM means grams per square metre, a rough measure of fabric weight. At 240, the micro-knit polyester is a substantial fabric and not a thin sports mesh. At 180, the spun polyester in the crop top is lighter, which suits a short cropped shape.

Where micro-knit polyester genuinely helps
It dries fast
Like all polyester, micro-knit polyester holds very little water inside its fibres. A tee that gets damp from a walk, a workout or a sudden shower dries far sooner than a cotton one. If you wash at night and wear in the morning, this matters.
It keeps a print sharp
A design that covers the whole garment, like the glyph grid, needs a fabric that takes ink evenly. Polyester does this well, which is why the all-over pieces in Street are made in it. Colours look clean and edges stay crisp.
It resists creasing
Packed in a bag, micro-knit polyester usually comes out flatter than cotton. For travel days, that is a real advantage. Our note on the Kaal Grid design covers how the grid is meant to be worn.
It is light on the wallet and the wardrobe
These pieces start at ₹599, which makes them easy additions for a second outfit or a gym bag, without competing with your everyday cotton.
Where cotton is better
Long, still, humid days
Cotton absorbs sweat and lets it spread through the fabric, so it feels less sticky against the skin. If you sit for hours in a room with poor airflow, or you live somewhere coastal, cotton usually feels more comfortable.
Skin that reacts easily
Some people find synthetic fabric irritating on sensitive skin, especially in heat. If that sounds like you, try one piece for a short period first, and keep cotton as your base layer.
Sleeping and lounging
For anything close to bedtime, cotton is the safer choice. Polyester is a daytime, active fabric for most people.
If you want a cotton alternative to the micro-knit polyester tee, the CORE Crew Tee is a 180 GSM cotton crew tee at ₹749, in a unisex regular fit. It is offered in Noor Black, Rui White and Agni Red.
A quick way to decide
| Your day looks like | Lean towards |
|---|---|
| Walk, game, gym, short errands | Polyester (Kaal Grid tee or shorts) |
| Travel by train, bus or flight | Polyester for creases, cotton if the journey is long and warm |
| Full day at a desk | Cotton |
| Heavy monsoon humidity | Polyester dries faster; cotton feels softer while you wear it |
| Evening out, warm but breezy | Either, and polyester keeps a print sharp |

Tips to wear micro-knit polyester in heat
- Pick the loose shape. Oversized and relaxed cuts leave air between fabric and skin, which is the main way polyester cools you.
- Wear it outdoors, not in still rooms. A little moving air makes a big difference.
- Wash it soon after wearing. Polyester can hold on to odour if left in a bag. Wash it inside out in cool water and dry it in shade, following the care label.
- Add a cotton tee under the shorts set only if you need it. Otherwise, keep the outfit to a single layer.
What we would say to a friend
If you want an easy, bold piece for a weekend outing, the Kaal Grid tee and shorts are a good match, and they are made to work as a set. If you want something to wear every working day, put cotton first and add micro-knit polyester for the days that suit it. Neither fabric is wrong. They are tools for different days.
How to think about GSM in polyester
GSM is easy to misread. In cotton, a higher number usually means a warmer, heavier hand. In micro-knit polyester, the weave and the yarn change the picture, so the same number can feel lighter than you expect. The Kaal Grid tee and shorts are both 240 GSM micro-knit, which gives them structure and a smooth drape, and the Rui Floral Crop Top at 180 GSM spun polyester is lighter because it is a short, cropped piece.
The practical advice is to judge by the shape and use. Try a polyester piece on a short day first, notice how it feels after an hour, and then decide how often it belongs in your week. This is the same approach we suggest for any new fabric.
Wearing the Rui Floral Crop Top in heat
The crop top is the lightest of the three. A cropped hem leaves your midriff open to air, which helps in heat, and 180 GSM spun polyester is not a heavy fabric. It suits a warm evening out, a festival afternoon or a casual day with high-waisted trousers or shorts. If you are unsure where a crop hem should land, our note on where a crop tee hem should land helps.

Each piece is made in India, for you, once you reserve it, and shipping is free across India.
FAQs
Is polyester too hot for Indian summers?
Polyester does not absorb sweat the way cotton does, so it can feel warm and clingy in still, humid air. It works better for short, active outings, in moving air, or in a looser shape.
What is micro-knit polyester?
It is a fine knitted polyester fabric with a smooth, light surface. The Kaal Grid Oversized Tee and Kaal Grid Shorts use a 240 GSM micro-knit polyester.
Is spun polyester different from micro-knit?
Spun polyester is made from shorter fibres spun into yarn, which gives it a slightly softer, more fabric-like feel. The Rui Floral Crop Top is 180 GSM spun polyester.
When should I choose cotton instead?
Choose cotton for long days, sitting still, or heavy humidity, where you want the fabric to take up sweat. The CORE Crew Tee is a 180 GSM cotton option at ₹749.
