What is the reason 3% polyurethane is included in the cap fabric?
Ball caps are often made only of cotton, so you may wonder what role the 3% polyurethane listed in the blend plays.
Centaur's ball cap adds a small amount of stretchy polyurethane to cotton to help softly and flexibly wrap around the head.
It is 3%. Centaur's CENTAUR BALL CAP_WINE has fabric woven with COTTON 97% and POLYURETHANE 3%[1].
Generally, ball caps made only of cotton fabric keep the shape of the cap firm, but because the fabric itself lacks elasticity, it easily puts pressure around the forehead when worn for a long time. Polyurethane is a representative elastic fiber that stretches and bounces back like rubber. Even when blended in just a small amount of around 3%, the fabric responds flexibly along the curves of the head.
It takes care of both structure and comfort. Without compromising the advantage of cotton that maintains a firm structure, this composition complements the fit so that it wraps lightly without pressing down on the head.
hmmm, while it looks like a firm ball cap on the outside, it is a calculated detail to wrap more softly when touching the head.

The exact measurements of the cap circumference and the adjustment method have not yet been confirmed.
