Pique polo shirt fabric generally has good breathability compared to many other dress fabrics. Here's a quick overview:

Breathability refers to how easily air and moisture can pass through a fabric. This impacts how comfortable and cool the fabric feels, especially during physical activity or in warm weather.

Pique is a lightweight, textured cotton fabric that is commonly used for polo shirts. The small, raised dots or "pique" pattern in the fabric creates small air channels that allow for better airflow and ventilation compared to smoother, more dense fabrics.

This makes pique polo shirts more breathable than many woven dress shirts made from fabrics like broadcloth, poplin, or dress shirting. Pique is also typically more breathable than heavier, less porous fabrics like wool suiting or canvas.

The breathability of pique can be further enhanced by choosing an open, loosely woven construction versus a tighter, more compact weave. Some performance-oriented pique polos may also incorporate moisture-wicking synthetic fibers to improve cooling and dry time.

Overall, the breathable nature of pique makes it a comfortable choice for warm weather, light physical activity, or situations where you want a more casual, airy feel compared to traditional dress shirts.
