Polyester vs. cotton running hats

Technical fabric or cotton — a straight side-by-side from the people who build running caps.

The short answer

Choose technical polyester for anything people will run in. It wicks sweat, stays light when soaked and dries fast, while cotton absorbs sweat, gains weight through the run and dries slowly. That is why Custom Running Hats builds running hats in technical fabric and says so on the quote when a brief points at the wrong material.

Where polyester wins

A running cap is judged at mile eight, soaked. Featherweight technical fabric, vent panels placed where heads dump heat and a sweatband that routes sweat to the temples are what make a cap comfortable for a whole run, and they are the core of our performance running caps. The same wicking build carries the reflective hits on reflective dawn and dusk caps and the colors on run club caps, and it survives repeated washing.

Where cotton still fits

Cotton is a perfectly good everyday fabric for a casual cap, but it is the opposite of what a running cap has to do, so we do not print running hats on it. If your brief is lifestyle merch and not athletic headwear, a different specialist will serve you better.

The verdict

Pick polyester for race caps, club caps, reflective caps and anything worn while running.

Skip cotton for running; it is heavy when wet and slow to dry.
