How breathable is polyester in hot weather?

 

 

Breathability Compared to Cotton

Polyester is a synthetic fabric and is less breathable than natural fibers like cotton. It doesn’t allow air to pass through as efficiently, which can make it feel warmer in hot weather.[1]

 

Moisture Vapor Transmission

Although polyester doesn't breathe as well as cotton, it can still allow some moisture vapor to escape. It does not trap sweat like cotton, but it doesn’t provide as much cooling effect.

 

Fabric Construction

The breathability of polyester can also depend on how the fabric is woven. Some modern polyester fabrics are engineered with micro-pores that allow better airflow, making them more comfortable in hot weather.

 

Fabric Breathability Best For
Cotton Very High Hot Weather, Casual Wear
Polyester Moderate Sports, Active Wear
Polyester Blends Moderate-High Durable, Everyday Wear

A comparative image showing two T-shirts: one made of cotton, with a soft and breathable texture, and the other made of polyester, featuring a smooth, synthetic surface. Both T-shirts are displayed in a warm outdoor environment with subtle visual indicators highlighting the breathability of each fabric. The cotton T-shirt is shown as more airy, while the polyester T-shirt is less breathable. The fabrics are labeled with their names, and air circulation symbols are used to emphasize their differing qualities. Soft natural lighting enhances the fabric textures.

How does polyester manage moisture in hot weather?

 

 

Moisture-Wicking Properties

Polyester is highly effective at moisture-wicking, meaning it draws sweat away from the skin and pushes it to the fabric surface, where it can evaporate quickly.[2]

 

Quick Drying

Polyester dries much faster than natural fibers like cotton, which helps keep you dry and comfortable during hot weather or intense physical activity.

 

Comparison with Other Fabrics

While polyester excels at moisture-wicking, it doesn't offer the same level of comfort as cotton for long periods of wear, as it can feel clammy once saturated with sweat.

 

Fabric Moisture-Wicking Drying Speed
Polyester High Fast
Cotton Low Slow
Wool Moderate Moderate

How comfortable is polyester in hot weather compared to other fabrics?

 

 

Comfort During Physical Activity

Polyester is commonly used in athletic wear due to its ability to wick moisture and dry quickly, making it more comfortable for sports and active wear in the heat.

 

Feel Against the Skin

Unlike cotton, which feels soft against the skin, polyester can feel less comfortable, particularly if it gets saturated with sweat. However, modern polyester blends have been designed for greater comfort.

 

Use in Performance Apparel

Polyester’s combination of moisture-wicking and durability makes it the preferred choice for performance T-shirts. It is less likely to stretch out or lose shape when compared to cotton under high temperatures.

 

Feature Polyester Cotton
Comfort Moderate High
Moisture-Wicking High Low
Durability High Moderate
