Cotton or Polyester for Kids in a Hot Climate?

We make almost everything in cotton, so treat this as a partial source. That said, polyester genuinely beats cotton at several things, and pretending otherwise would be useless to you.
Side by side
| Cotton | Polyester | |
|---|---|---|
| Breathability | Wins | Air moves through less freely |
| Odour after a day | Wins clearly | Holds smell; the known weakness |
| Drying time | Slower | Wins easily |
| Weight | Heavier | Wins |
| Ageing | Softens | Pills, and does not recover |
| Cost | Higher | Wins |
Where polyester is the right answer
Sportswear, honestly. If a child is running for an hour and sweating hard, a technical synthetic moves moisture away faster and dries before the drive home. Swim kit and rain layers likewise. There is no cotton argument there.
It is also cheaper, and for fast-growing children on a budget that is a real consideration, not a weak one.
Where cotton wins here specifically
Everyday wear in the Gulf is not a sport. It is short bursts of intense heat between long stretches of air conditioning, repeated all day. Cotton absorbs moisture into the fibre and lets it go slowly, so a child does not walk into a cold classroom wearing a wet layer.
And odour is not a small point with children. Polyester's structure holds the bacteria responsible, which is why a synthetic hoodie can smell after one wear and a cotton one does not. In a household doing daily washing in summer, that decides how often a garment goes through the machine, and therefore how long it survives. The fabric detail is in what cotton futer is.
