3:00Now PlayingEveryone has an opinion about the best fabric for hot weather—but do different materials actually keep you cooler?
In this episode of Field Proof, our outdoors editor, Kai, tests six sun hoodies made from six different materials to find out whether one fabric really performs better than the rest. From natural fibers to high-performance synthetics, each hoodie is put through the same series of tests to discover what actually makes a material feel cooler.
We test each hoodie for:
Moisture wicking
Drying speed
Airflow
Heat retention
Real-world cooling feel after a one-mile run
By the end, we'll answer whether some materials genuinely keep you cooler, why certain fabrics perform better than others, and which one we'd actually recommend for hiking, running, and hot summer days.
