Heat management is physics: airflow plus moisture handling. Here is the honest ranking for hot weather, from coolest to sweatiest.

## 1. Linen

The open weave and hollow flax fiber move air better than anything else in common use. Linen also absorbs a fifth of its weight in moisture before feeling damp. The wrinkles are the price of admission. 10/10 cool.

## 2. Seersucker

The puckered weave holds most of the fabric off your skin, creating micro air channels. Traditionally cotton, so it absorbs well too. Criminally underused outside the American South. 9/10.

## 3. Lightweight cotton (poplin, voile, chambray)

Breathable and absorbent, but it holds moisture against you once soaked - in humidity, a wet cotton tee stays wet. Fine for dry heat, sticky in tropical conditions. 7/10.

## 4. Tencel/lyocell

Absorbs better than cotton and feels cool to the touch, with a drape that flatters. Loses points only for slightly less airflow than linen. 7/10, higher if you hate wrinkles.

## 5. Merino wool (lightweight)

Counterintuitive but real: 150-190gsm merino regulates temperature and handles sweat vapor better than cotton. The traveler's choice. 6/10.

## 6. Polyester and nylon

They dry fast but breathe poorly and trap odor - in heat, a polyester shirt is a personal greenhouse. Performance weaves with wicking finishes help briefly, then wash out. 3/10. Avoid for all-day summer wear.

## Buying rule

For true heat: 100% linen or a linen-cotton blend, light color, loose weave you can see light through. Everything else is a compromise.
