Polyester Shirts: Cons in Hot Weather

Poor Breathability

Trapped Heat

You may notice that polyester shirts often feel warmer than shirts made from natural fibers. Polyester does not allow air to flow freely through the fabric. When you wear a polyester shirt in hot weather, your body heat gets trapped. This lack of breathability can make you feel sweaty and uncomfortable, especially if you spend time outdoors or in direct sunlight.

Polyester fibers create a tight weave that blocks airflow. Your skin cannot release heat as easily, so you may experience a buildup of warmth. If you compare polyester to cotton or linen, you will find that natural fibers let air pass through more easily. This difference helps your body cool down faster and prevents overheating.

If you want to stay cool in hot weather, you should choose shirts made from breathable fabrics. Cotton and linen allow heat to escape, while polyester tends to trap it.

Heat Retention

Overheating Risk

Polyester shirts can increase your risk of overheating in hot climates. The fabric holds onto heat and does not absorb moisture like cotton or linen. When you sweat, polyester wicks moisture away but does not cool your skin as effectively as natural fibers.

• Polyester exhibits lower sweat retention because it wicks moisture away from your skin. You stay drier, but the fabric does not help release heat.

• Cotton absorbs more moisture, which can make you feel damp. However, cotton also releases heat quickly when it gets wet, helping your body cool down.

• During exercise, cotton clothing shows sudden increases in surface temperature due to moisture absorption and heat release. Polyester does not show this effect, so it retains heat more consistently.

You may feel hot and sticky if you wear polyester shirts for long periods in the sun. The fabric’s heat retention can lead to discomfort and even heat-related health risks. If you work outdoors or exercise in hot weather, you should consider how your shirt’s material affects your body temperature.

Odor Issues

Sweat Smell

Polyester shirts often develop strong odors after you sweat. The synthetic fibers create an environment where odor-causing bacteria can thrive. You may notice that polyester shirts smell more intense and unpleasant than cotton shirts after physical activity.

• Polyester shirts retain and promote the growth of odor-causing bacteria more than cotton shirts. You may experience a musty, ammonia-like, or sour smell.

• After exercise, polyester T-shirts have a significantly lower hedonic value compared to cotton T-shirts. This means they smell less pleasant and more sweaty.

• The odor from polyester shirts is often described as strong, sweaty, and sour. Micrococci bacteria grow more on polyester fabrics, which increases the smell.

If you want to avoid sweat odors, you should choose shirts made from natural fibers. Cotton and linen do not trap bacteria as easily, so they stay fresher for longer. Polyester shirts may require frequent washing and special care to prevent unpleasant smells.

Tip: If odor is a concern for you, look for shirts with antimicrobial treatments or choose natural fibers for better freshness in hot weather.

Skin Sensitivity

Irritation Potential

You might notice that polyester shirts can irritate your skin, especially in hot weather. Polyester does not breathe as well as natural fibers. When you sweat, the fabric traps heat and moisture against your skin. This environment allows bacteria to grow, which can lead to itching, redness, or even flare-ups of skin conditions like eczema.

• Up to 28.5% of clothing industry workers develop contact dermatitis from fabric exposure.

• About 80% of contact dermatitis cases come from irritants, including chemicals and dyes in clothing.

• Synthetic fabrics like polyester often trap heat and sweat, increasing the risk of skin irritation.

• Polyester’s tight weave and chemical treatments can make it uncomfortable for people with sensitive skin.

If you have sensitive skin, you may feel more comfortable in shirts made from cotton or linen. These natural fibers allow your skin to breathe and reduce the chance of irritation. The choice of fabric and the chemicals used in its production play a big role in how your skin reacts, especially during hot and humid days.

Environmental Impact

Sustainability Concerns

Polyester shirts raise several environmental concerns. The production process uses non-renewable resources like oil and releases more greenhouse gases than natural fibers. Polyester does not break down in the environment, so it contributes to microplastic pollution. When you wash polyester shirts, tiny plastic fibers can enter waterways and harm marine life.

Here is a comparison between polyester and cotton shirts based on key environmental criteria:

You can see that polyester uses more energy and produces more greenhouse gases than cotton. However, cotton requires much more water and can cause land degradation. Both fabrics have sustainability challenges, but polyester’s lack of biodegradability and microplastic pollution make it a bigger concern for the environment.

• Polyester is less breathable than natural fabrics, which can make you uncomfortable in hot weather.

• The material traps heat and odors, making it less suitable for warm conditions.

• Polyester can trap bacteria against your skin, increasing the risk of irritation.

• The tightly woven fabric does not allow for proper ventilation, which can make hot weather feel even hotter.

• Polyester production emits more greenhouse gases and creates microplastics, raising sustainability concerns.

Note: When you choose a shirt, consider both your comfort and the impact on the environment. Natural fibers like cotton and linen may offer better breathability and a smaller environmental footprint, especially in hot weather.
