When it comes to choosing our clothes, especially those we intend to work out in, the fabric plays a critical role. We want materials that are not just aesthetically pleasing, but also functional and comfortable. This is particularly true for running shorts, where comfort and performance go hand in hand. Among various fabrics, one common material you’ll often encounter is polyester. But, is 100% polyester hot to wear? Let’s unravel the truth behind this question.

Understanding Polyester

Before we dive into the heat factor, let’s take a brief moment to understand what polyester is. Polyester is a type of synthetic fabric derived from petroleum products. Known for its durability, resistance to wrinkles and shrinking, and affordability, polyester has become a popular choice in the clothing industry, especially in sportswear.

Polyester and Heat: A Complex Relationship

So, back to the burning question: Is 100% polyester hot to wear? The answer is complex because it depends on various factors, including the weave of the fabric, the garment’s design, and the wearer’s personal comfort and heat tolerance.

Polyester’s Heat Retention

Polyester has a reputation for being less breathable compared to natural fabrics like cotton, which can make it feel hotter to some people. The material is inherently non-absorbent, meaning it doesn’t absorb sweat. Instead, it wicks moisture away from your skin and pushes it to the garment’s surface where it evaporates. While this property makes polyester great for rain jackets and swimwear, it can create a plastic bag-like effect when wearing a 100% polyester garment on a hot day, trapping heat close to your body.

The Role of Weave and Design

Not all polyester garments are created equal. The heat factor can significantly be influenced by the weave of the fabric and the design of the garment. For instance, a loosely woven polyester fabric or a polyester mesh can be much cooler than a tightly woven one. Similarly, a loose-fitting running short made of polyester can feel cooler than a tight-fitting one because it allows for better air circulation.

Personal Comfort and Heat Tolerance

Finally, whether 100% polyester feels hot to wear can also come down to personal comfort and heat tolerance. Some people might not mind the reduced breathability and might prioritize the durability and moisture-wicking properties of polyester, while others might prefer natural, breathable fabrics.

Making Polyester Work for You

If you’ve decided to stick with polyester running shorts despite their potential heat factor, there are ways to make them work for you:

  • Choose the right design: Opt for loose-fitting designs that allow for better air circulation.
  • Look for blended fabrics: Polyester blends can offer the benefits of polyester while mitigating some of the heat retention issues. For example, polyester blended with cotton or linen can provide a more breathable option.
  • Opt for moisture management technology: Many sportswear brands offer polyester garments featuring moisture management technologies that enhance the fabric’s wicking properties, making them more comfortable for sweaty workouts.


So, is 100% polyester hot to wear? The answer isn’t straightforward. While polyester’s lack of breathability compared to natural fabrics may make it feel hotter to some individuals, factors such as the garment’s design and the wearer’s personal comfort can significantly influence the experience. With the right choices, polyester running shorts can be a practical option even in warm conditions.

Frequently Asked Questions (FAQs)

Does polyester make you sweat more?

Polyester itself doesn’t make you sweat more. However, because it is less breathable than some other fabrics, you might feel hotter and sweatier if you’re wearing 100% polyester clothing in warm conditions.

Is polyester good for hot weather?

Polyester can be suitable for hot weather if it’s designed with a loose fit or blended with other breathable fabrics. It also has excellent moisture-wicking properties which can be beneficial in hot weather.

Can you run comfortably in polyester shorts?

Yes, many runners wear polyester shorts because they’re durable, lightweight, and great at wicking away sweat. However, some might find them less breathable than shorts made from natural fabrics.

Why do we use polyester in athletic wear?

We frequently use polyester in athletic wear because of its durability, resistance to wrinkles and shrinking, lightweight, and excellent moisture-wicking properties.

Is wearing polyester bad for your skin?

Wearing polyester isn’t typically harmful to your skin. However, if you have sensitive skin or are prone to heat rash, you might find natural, more breathable fabrics more comfortable, especially in hot conditions.
